1) NYC and SF are symptoms of runaway gentrification caused by a grossly overpaid tech and finance sector. The housing prices there are artificially inflated, a bubble built on top of the speculation-driven advertising economy we find ourselves in in 2022. They are not at all representative of the typical American's lives and shouldn't be used to make public policy.
2) The professional classes already have way more mobility and options, in terms of where to live, where to work, how to work, etc. They/we don't need the same degree of protections that the working class does. To even be in the professional caste is already a rarity in today's America.
3) Tax brackets are already marginal anyway. If you earn $400k, that means you pay 32% of the first $215,950, and 35% only on the the remaining $184,050. If you just add more brackets at the top, you wouldn't much affect your typical upper-middle-class professional or business owner.
4) The politicians don't care about working conditions at all. We're too busy being distracted by the culture wars to pay attention to class at all =/
