EXAMPLE: 120k income breakdown:
Federal actual rate 16.5% (24% marginal)
CA State actual rate 6.4% (9.3% marginal)
Medicare rate 2.9%
OSDI rate 12.4 %
CA SDI rate 1.0%
= 39% right there
PS the highest marginal tax rate in the US is 50.3%.
Federal rate of 37% and California rate of 13.3%.
I still don't think there's an affordability crisis in general though. From what I've seen in this thread it's more of an inability to downsize. Everyone needs a car (sometimes 2), a big house, to live in the most expensive cities, to have kids, and they'd rather go into debt than compromise.
There might be a big step between poor and middle class though, as you come off benefits and have to pay higher taxes and health insurance. Child care also seems prohibitively expensive.
I'm also very suspicious that it would cost 40K per year to rent a reasonable place for 1 or 2 people anywhere in the US except maybe SF
