In US your income is high, but costs are very high as well, hence $1 mil is a surprisingly smaller amount of money that you might imagine otherwise.
In addition, the tax is proposed to be coming now and improvements later, but so far I personally haven't seen ANY improvements in government/state services here in the last, say, 30 years, give or take. They will spend the money as they will see fit.
It's still a good bit of money. Granted it's easy to have one's lifestyle "adjust" to where a million a year is "pin money" but at that point you have other issues to deal with.
In terms of Govt spending, well we did get one hell of a 20+ year fake "war" for our $$$ and I am impressed so far with my COVID shots....
