California is trying to catch up.
The problem is they will still vote leftist
Unfortunately California is ahead.
The current California top rate is 9.3% @ about $100k and they are trying to raise it come November.
It is an interesting dilemma. The ones that stay are not capitalists, they are the ones living on the teat. So they will accelerate the move to government welfare. The ones that leave, leave with their capitol, and I suspect tend to vote more and more conservative these days. The ponzi scheme of shifting the Republic to a Democracy is beginning to show some serious cracks in the foundation.
