“The Skateboarding Ethic and the Spirit of Anti-Capitalism.” That was the title of an unusual paper presented at the annual meeting of American economists this year. The title was clearly a reference to a famous 1905 book by German sociologist and economist Max Weber, The Protestant Work Ethic and the Spirit of Capitalism. And I really wanted to know what this economist was going to argue, and, even more, who he was.
This year’s economics conference was spread out across hotels around San Francisco’s Union Square. On the first day of the conference, it was raining hard, and I ran from my hotel to another one down the street to see this paper be presented.
Sopping wet, I entered a small, basement conference room before the presentations began. “Is this where the skateboarding paper is being presented?” I asked the room.
Sure enough, a Gen Xer with baggy blue jeans, Vans skate shoes, and a tweed blazer with elbow pads — the only fashion item that screamed “I’m an academic” — stood up and turned around. “Yes, I’m presenting the skateboarding paper here,” he said.
This tweed-jacketed, Vans-wearing man was Thomas Kemp. He’s an economist at The University of Wisconsin–Eau Claire. Kemp says he’s been skateboarding for 40 years, and he continues to skate every day he can (it gets harder to skate during Wisconsin’s winters, so Kemp says he snow skates as well).
For a long time, Kemp published pretty standard economic papers. Papers with titles like, “The Impact of Water Clarity on Home Prices in Northwestern Wisconsin” and “Estimation of product price elasticity of demand.”
“When I was a graduate student, I was actually going to write about skateboarding, but I was told ‘that’s not a good idea,’” Kemp says. But Kemp is more established now. In fact, he’s the chair of his economics department, so he’s more willing to ollie onto the topics he’s the most passionate about.
Kemp’s transformation began a few years back, when he discovered the burgeoning academic literature on skateboarding. “I was just blown away, like, ‘Wow, people are doing academic work on skateboarding,’” Kemp says. And that’s when he did his 180 kickflip.
“ I literally dropped everything else I was working on and started writing papers on skateboarding,” Kemp says.
The Value of Skateparks
Kemp has now published a series of economic papers about skateboarding. One paper, recently published in The Journal of Economic Analysis, is titled “Shred Central: Estimating the user benefits associated with large public skateparks.” Kemp estimated the consumer benefits of the Lauridsen Skatepark in Des Moines, Iowa. At 88,000 square feet, it’s the largest skatepark in the United States.
One of the issues with the economics of skateparks is they’re generally free to use, which makes it difficult to figure out how much they’re actually worth. This is a common problem for public goods, like parks, beaches, rec centers, and so on. Determining the value of a skatepark is important to figure out whether, for example, communities should build more skateparks, and how big and tricked-out those skateparks should be. Despite the popularity of the sport — estimates suggest there may be as many as 9 million skateboarders in the US — “public resources devoted to skateboarding lag far beyond other leisure activities such as softball, tennis, or soccer,” Kemp writes.
Kemp argues that the distance skaters (and BMXers, roller bladers, and other recreationists) are willing to travel to go to the skatepark provides a good way to estimate the value of it. Traveling requires time and money, so the distance users are willing to travel provides an indication of how much they think a skatepark is worth.
In “Shred Central,” Kemp surveyed skateboarders at Lauridsen Skatepark, and found they “will travel great distances at significant cost to ride a park of high perceived quality.” Crunching numbers on use of the park and travel distance, Kemp estimates that the user benefits of this skatepark are “$61 per user per day and roughly $488,000 annually.” This high estimate for the value of the skatepark suggests that there’s a shortage of high-quality skateparks around the country and that community leaders should build more of them. Rad!
“The Skateboarding Ethic and the Spirit of Anti-Capitalism”
In his 1905 book, The Protestant Work Ethic and the Spirit of Capitalism, Max Weber argued that Protestant Christianity, especially Calvinism, promoted ethics, like thrift and hard work, that helped nurture the birth of capitalism and rapid economic growth in Northern Europe.
Like Protestants, skateboarders, Kemp argues, have their own set of ethics that can affect their economic lives. And, in Kemp’s view, these ethics can come into conflict with capitalism. For example, skateboarders are known to skate on private property and in front of businesses in search of cool, skateable features. It’s one reason why community leaders have been building skateparks: to encourage skaters to skate in sanctioned areas that are less disruptive to business.
Kemp sees a similar process in history with stickball and baseball. During his presentation, Kemp showed a picture of baseball legend Willie Mays playing stickball in the street when he was young. Like with skateboarding, Kemp says, many leaders saw stickball as a nuisance that disrupted commerce. Kids would shut down streets and disrupt traffic to play the game. They would hit balls and dent cars and break windows. This “irritation to commerce,” Kemp suggests, inspired communities to start building baseball diamonds in community parks and institutionalize the game into more organized and less disruptive baseball leagues.

“The drive towards creating skateparks appears to me to be on a similar trajectory to what we saw with stickball into baseball,” he says. “That said, we’re now 50-plus years into skateboarding history, and so far, skateboarding seems to be relatively immune from that institutionalization. It’s just as common to see kids skateboarding out in the streets as it is in a skatepark, perhaps even more so.”
Kemp was the last person to present a paper during this particular conference session. The paper presented before him was much less fun, highlighting physical and mental health problems plaguing our society, including the rise of depression, anxiety, and deaths of despair. The author blamed our economic and health systems, which “prioritizes profits over people’s health,” for making these problems worse.
In important ways, skateboarding is a product of capitalism. For decades, for-profit companies have developed and manufactured better skate decks, trucks, and wheels. They’ve marketed the sport. They’ve popularized it. They’ve made it more accessible. Kemp acknowledges that. But he also sees ethics within the culture of skateboarding that can help people overcome the challenges they may face in our capitalist society.
The skateboarding ethic, Kemp says, is “an ethic of resiliency. I fall, I get up, I do it again.” It’s an ethic of “self-betterment. The skateboarder is always trying to do another trick. They’re trying to do the trick better with more style. They’re trying to do it in different places. They’re comparing themselves to their past selves and not necessarily other skateboarders.” And it’s an ethic that isn’t really concerned with competition with others. Skateboarding, he says, is a non-zero sum game. “In other words, if I do the trick, it doesn’t matter that the other skateboarder didn’t do the trick. I’m not in competition with them. I don’t win, they lose, or I lose, they win. No, we’re all winning — hopefully — compared to our previous selves.”
Skateboarding, Kemp suggests, can help us become more resilient. It can help us build more pride in ourselves. It can help us fight isolation and build community. And it can help us exercise, alleviate stress, find joy, and escape the 9-5 grind.
“Skateboarding has something to show us about living life in these challenging times that we find ourselves in,” Kemp says.
Kemp’s presentation, appropriately, took place in San Francisco, which is widely recognized as one of the best and most hardcore skateboarding cities in the world. Skaters here are known to “bomb” hills like daredevils, reaching high speeds and doing incredible tricks. And the city has really come to embrace skateboarding. For example, the San Francisco Museum of Modern Art currently has a skateboarding exhibit called “Unity Through Skateboarding” (which, apparently, my son and wife really enjoyed while I was attending this conference).
“San Francisco is legendary,” Kemp said. “Of course, this is a work trip. But, hopefully, I’ll get some skating in while I’m here.”

Waymo called the cops on teen riders, raising privacy concerns

Police in San Mateo, Calif., posted Monday on social media that they had apprehended a pair of teenagers from a Waymo driverless robotaxi after the company alerted authorities to suspected criminal activity. It’s the latest incident involving video surveillance of passengers and others by autonomous vehicles — raising questions about the limits of privacy in such vehicles.

The Facebook post by the San Mateo County Police said: “Parents do you know where your teens are? @waymo does!”
The 15-year-olds were allegedly drinking alcohol and shooting toy guns from the car, according to the police. They said Waymo’s systems detected behavior that then triggered a safety response, after which the company disabled the vehicle and contacted police.
Waymo’s cars, equipped with an array of cameras, microphones and other sensors to monitor passengers and other nearby vehicles, are becoming more common in cities across the United States. Experts say the detention of the two teens in San Mateo highlights a potential — but not inevitable — trade-off between privacy and convenience. It also questions the extent to which companies similar to Waymo are required to hand over private data, including audio and video of passengers, in situations where a crime is suspected.
NPR reached out to Waymo, which is owned by Alphabet, the parent company of Google, for comment on the details of the San Mateo incident and how the company responded, but did not hear back. But on its website, the company says that as many as 29 cameras in its autonomous cars provide an all-around view and “are designed with high dynamic range and thermal stability, to see in both daylight and low-light conditions, and tackle more complex environments.”
“There already exist laws that govern duty to report or even duty to protect” for carriers such as Waymo, according to Alessandro Acquisti, a professor of information technology at the MIT Sloan School of Management. “The privacy problems arise when and if driverless carrier companies used such laws or ethical obligations as a pretext for blanket, indiscriminate accumulation of identifiable data for unspecified future purposes.”
That includes not just monitoring people inside the cars, but outside too. Take, for example, a hit-and-run investigation last year in Los Angeles. Media reported that the police inquiry was aided by video captured by a Waymo taxi that had a clear view of the crime. Critics suggested at the time that authorities were using the company’s vehicles as a mobile surveillance platform. And during 2025 protests in Los Angeles against Immigration and Customs Enforcement crackdowns, demonstrators vandalized Waymos, apparently angry that video recorded by the vehicles could be used by police, although there is no evidence that happened.
In a transparency report, Google says it received nearly 290,000 requests from governments worldwide in the first six months of 2025 for disclosure of user information across all its platforms, including Waymo. The company says that in more than 80% of the requests in those six months, some information was disclosed. “Google carefully reviews each request to make sure it satisfies applicable laws. If a request asks for too much information, we try to narrow it, and in some cases we object to producing any information at all,” the company says.
In an email to NPR, San Mateo Police Department spokesperson Jeanine Luna said that detaining the teens in the Waymo on Monday was “wholly appropriate” under the circumstances. “We received the call of a ‘firearm’ being shot from a moving vehicle,” she said. “Furthermore, the occupants were described as being possibly ‘intoxicated.’” she said.
“Being that the vehicle was disabled (the occupants had every right to exit the vehicle before police arrival, but they did not), a high-risk traffic stop was conducted to ensure the safety of all involved,” Luna added. “They were not arrested and were released to their parents, however, potential charges are still pending dependent on what the video from inside the vehicle shows.”
Autonomous taxis represent an ethical gray area
Robotaxis began to roll out across the U.S. in December 2018, when Waymo launched in Phoenix. These services have been used for less than a decade — so the norms surrounding them aren’t settled, experts agree.
The Facebook post may make Waymo passengers wonder what triggers a police intervention, says Irina Raicu, director of the Internet Ethics program at Santa Clara University. She has used Waymo’s driverless taxis and says ethically, the privacy issues surrounding them sit in a gray area. “There’s something about being in a car without another person that makes you think it’s private.”
“With all these recording devices, we don’t see them, [and] they’re not these obvious things being stuck in our faces,” Raicu adds.
That brings up a key issue: informed consent, Acquisti says.
“It is not clear the extent to which passengers … are reminded that when they step into the car, that they are being monitored, and most likely they are not told in its entirety how the data will be used,” he says.
Bruce Schneier, a cybersecurity and privacy expert and professor at the Munk School at the University of Toronto, believes that Waymo does have a compelling interest in protecting its vehicles. He compares monitoring a robotaxi via cameras to a human taxi driver keeping an eye on passengers in the rearview mirror.
“Maybe the driverless car comes back … and it has all of its cushions slashed, and it’s like, ‘Who the hell did that? Let’s go and look at the tape,’” Schneier suggests. “You can’t have sex in the back of a taxi, right? Someone would say, ‘Stop it.’”
He concludes that some supervision makes sense. In an Uber rideshare, he notes, “most of the time there’s a camera recording the back seat.” (Uber says on its website that it allows drivers to install such cameras for the purpose of “fulfilling transportation services.”)

Waymo robotaxis, while a fairly common sight in the San Francisco Bay Area, are still a novelty in much of the country. And many people are hesitant to ride in one, according to a Pew Research Center poll published this month. The survey found that only 5% of Americans had ever ridden in a driverless car. Meanwhile, 71% of those polled said they would feel uncomfortable in one, with only 7% saying they would be “extremely or very comfortable” riding in one.
For that reason, experts who spoke with NPR said they were optimistic that it’s not too late to shift gears on privacy norms and policies surrounding these vehicles.
Acquisti doesn’t see why privacy measures can’t be built into driverless vehicles.
“I would immediately challenge the notion that people have to be monitored,” he says, noting that privacy-preserving technologies exist and can be installed.
“Driverless cars are coming, but they don’t have to come in this particular incarnation,” Raicu says. “They’re still being designed and redesigned. It’s early days.”

Trump fires last members of election commission, inciting fears of midterm ‘chaos’
Donald Trump has terminated the remaining members of the independent, federal commission that assists election administration officials nationwide just a few months before the midterm elections, multiple outlets reported Thursday.
The remaining three commissioners of the four-member bipartisan commission were forced out on Thursday in different ways. The one Republican appointee resigned and the other two, Democratic appointees were notified of their terminations via email from the White House presidential personnel office.
“On behalf of President Donald J Trump, I am writing to inform you that your position as Commissioner of the Election Assistance Commission is terminated, effective immediately. Thank you for your service,” the email, seen by Reuters, said.
The White House did not immediately respond to a request for comment.
The Election Assistance Commission serves as a “national clearinghouse of information on election administration”, accredits testing laboratories and certifies voting systems, and maintains the national mail-voter registration form developed by the National Voter Registration Act of 1993, according to the commission’s website. The terminations follow Trump and top administration officials’ advocacy to change vote-by-mail requirements and investigations into the 2020 election outcome, which Trump lost to Democrat Joe Biden.
“It is irresponsible and dangerous that this Administration remains dead set on causing chaos for our election officials across this country,” Arizona secretary of state Adrian Fontes said in a Thursday statement. “This move undermines the integrity of nonpartisan election administration.”
The 2002 law that established the commission, the Help America Vote Act, states the president can appoint replacements to the commission.
It is unclear how Trump will move ahead with the commission.

Former Olympian pleads not guilty in reflecting pool vandalism charges

Former U.S. Olympic canoeist David Hearn pleaded not guilty to damaging the Lincoln Memorial Reflecting Pool in D.C. Superior Court Thursday morning.
Federal prosecutors charged Hearn with a single count of destruction of property causing more than $1,000 in damage to the pool.

Hearn has previously claimed, which his attorneys repeated during a short press conference outside the court, that he simply touched the water in the pool out of curiosity.
The Trump administration had just completed a $14 million renovation of the pool.
But shortly after the work finished, peeling paint and algae gathered in the water. The remodel has been largely criticized as a massive failure and waste of taxpayer dollars.

Superior Court Judge Carmen McLean released Hearn on his own recognizance. His next hearing is scheduled for Aug. 5.
Norm Eisen, one of Hearn’s attorneys, spoke to reporters outside of court following the hearing. He said the administration is using Hearn as a “scapegoat … for their own failures.”
“It is not a crime to touch the reflecting pool, to touch water in the United States of America,” he said.
Prosecutors say there is a host of evidence against Hearn.
This is a developing story.
