If someone told me a semiconductor shipment was late because it was the wrong phase of the moon, I would not have believed them before reading this paragraph!

Let's take a look at how Seattle's DoorDash law actually turned out.

In 2024, Seattle implemented "PayUp" — a minimum wage law for food delivery drivers, setting the rate at $26.40/hour. The intent was to protect workers. Here's what actually happened:

DoorDash added a $5 fee to every order. Customers stopped ordering. Within two weeks, 30,000 fewer orders. UberEats volume dropped 30%. Drivers — the people the law was supposed to help — saw their available deliveries cut in half and earnings per hour fall 25%.

A new National Bureau of Economic Research study confirmed what the numbers already showed: higher per-delivery pay was completely offset by fewer deliveries and lower tips. Active drivers saw zero net gain in monthly earnings.

KUOW reported this week that two years in, the results are undeniable — Seattle is now the most expensive delivery market in the country. Denver, Portland, and San Francisco, cities without these laws, saw delivery revenue grow 20-40%. Seattle stagnated.

The parallel to what's happening with WA tax proposals is obvious. SB 6346 would impose a 9.9% income tax on high earners. The QSBS add-back bills would strip federal tax exclusions from founders. The argument is always "just a small tax on those who can afford it." But capital moves. Founders move. Companies incorporate elsewhere.

The DoorDash data gives us a controlled experiment: same company, same product, same time period, different policy environments. The city with the heaviest regulation saw the worst outcomes — including for the workers it tried to protect.

Incentives matter. Every time.

In 2023 I was asked by @NatureAstronomy to suggest alternate reviewers from "underrepresented communities". I politely declined; deviating from expertise as the criterion damages our trustworthiness.

The editor responded that "... the Western/white/male worldview is ingrained into everything we do. We are working to counteract that bias by encouraging the voices of non-Western, non-white men to be heard."

The article was about measuring the size of the Milky Way galaxy.

Every argument progressives made against the intuitive broad definition of free speech in 2014-2021 is now being weaponized against them.

No one could have predicted this, it's a total surprise

"Test-optional" policies both A) let unqualified people into universities, and B) disadvantage actually qualified people from poor minority backgrounds.

Dumb policy.

What does America get from foreign students?
- They subsidize American students' education
- They inject life into small towns across America
- They do a large portion of America's STEM research

@JamesSurowiecki “Trade deficits are evidence for trade barriers” is the same fallacy as “unequal outcomes are evidence for racism.” Different ideology, same reasoning
