To remind ~150K earners pay ~50% of CA taxes.
Let that sit in your mind 1st, then ask yourself if ~1/2 of those flee to where it is better for them, the effect is and can only be either or both; worsening of health care and/or further raising the taxes. This is known effect that happens. Major HighTech companies are disincentivized and are already taking difficult decision. The question is when the avalanche effect happens? If it happens or if it is gradual race to the socialist bottom, then you can moralize 'til the cows come home, but guess what they won't be coming back.
Silicon Valley CAN become Detroit and it is already on initial phases of the path in that direction, although still far. Capacity of derangement of the CA government is not yet reached and ~70% Blue is not making any constructive dialogue to balance things here.
I am high earner and for a while I can bear still ok health care here and then I could enjoy early retirement (i.e. freedom 55) with this new socialized HC while it is still "ok". After a while I guarantee it will go worse and even I will be forced to re-evaluate and possibly move.
