Epstein case: 'The beauty of young women operates as a marker of status' OP-ED. American sociologist Ashley Mears, a former model, explains in an op-ed that the normalized presence of women alongside wealthy men provides them with 'a form of capital that wealthy men can mo...

“An abundance of girls functions as a form of capital that wealthy men can mobilize to build ties among themselves…
In [this system], men endowed w/ wealth extract value from young women's *bodies* w/ a disturbing degree of impunity, permitted through the value system of our society.”🧪

While most people prefer equal inheritance, wealthy individuals are more willing to support unequal transfers when they help preserve wealth across generations ➡️ based on new experimental evidence now published with @natrinh.bsky.social and @dariatisch.bsky.social in @sfjournal.bsky.social

The pace at which US wealth concentration is rising is simply staggering

The concentration of AI wealth into the hands of a few tech barons + plutocratic capture ==> unchartered territory

Tracking ICE's Profits ICE is extraordinarily costly to working people & grotesquely profitable for the worst among us

"Captain Gains" on Capitol Hill
Shang-Jin Wei & Yifan Zhou
WORKING PAPER 34524
DOI 10.3386/w34524
ISSUE DATE November 2025
Using transaction-level data on US congressional stock trades, we find that lawmakers who later ascend to leadership positions perform similarly to matched peers beforehand but outperform them by 47 percentage points annually after ascension. Leaders' superior performance arises through two mechanisms. The political influence channel is reflected in higher returns when their party controls the chamber, sales of stocks preceding regulatory actions, and purchase of stocks whose firms receiving more government contracts and favorable party support on bills. The corporate access channel is reflected in stock trades that predict subsequent corporate news and greater returns on donor-owned or home-state firms.

Fossil fuel billionaires are bankrolling the anti-trans movement An investigation shared exclusively with Atmos and HEATED finds that 80% of anti-trans organizations receive fossil fuel funding.

Excellent reporting from Heated and Atmos.

It looks like some of the biggest investors in the anti-trans movement are fossil fuel billionaires who are trying to use trans issues to ensure that Republicans pass policies favorable to their industry.

‘It’s a complicated time to be a white Southerner’ − and their views on race reflect that How do white Southerners think about their racial status in a world that is scrutinizing white advantages? Researchers found people across the political spectrum grappling with what being white means.

For The Conversation, I wrote about how White Southerners are making sense of what it means to be White in these times.

In a nutshell, it’s complicated.

I hope you’ll read and share widely.

The thing about charging him with assault for throwing a sandwich is that it exposes the historic lie of “assaulting an officer.”

This Tuckahoe home won a $1.26 billion contract for an ICE detention center. The owner isn't talking. The company’s website is dated and largely accessible only via login.

how much of the money from the ICE/tax cuts bill is just going to go to scammers, do you think? www.richmonder.org/this-tuckaho...

We must see that our lives, our struggles and successes, are bound up in each other. What does collective action look like if you stop being optimistic your discipline's market will improve and instead think about academia as a whole?
