Looking at discourse around California's ballot proposition 25-0024 (a "billionaire tax"), I noticed a pretty big world model mismatch between myself and its proponents, which I haven't seen properly crystallized. I think proponents of this ballot proposition (and wealth taxes generally) are mistaken about where the pushback is coming from.
The nightmare scenario with a wealth tax is that a government accountant decides you're richer than you really are, and sends a bill for more-than-all of your money.
The person who is most threatened by this possibility isn't rich (yet), they're aspirationally upwardly-mobile middle class. If you look at the trajectories of people-who-made-it, especially in tech and especially in California, those stories very frequently have a few precarious years in them in which their accessible-wealth and their paper-wealth are far out of sync. That happens with startup founders (a company's "valuation" is an artifact of the last negotiation you had with investors, not something you can sell). And it happens with stock options (companies use these to pay people huge amounts of money, without accidentally triggering an immediate retirement, and without needing to have the money yet). This sets up situations where, if the technicalities work out badly, a "5%" tax can make you literally bankrupt.
When people talk about "fewer businesses being created", this is why. If I were a billionaire, and I lost 5% of it to tax, I wouldn't care. If I were following a precarious, low-probability path towards becoming a billionaire, and I thought California would spring a kafkatrap to destroy me as soon as I got close, I would either not try, or not try in California.
In a different state, this might not be a credible fear. But California is a state that is famous for its kafkatraps, and for refusing to ever back down from the kafkatraps it's built.
