The top 1% in the US is ~400K USD.
Real question for OP (and others): What do you think is a reasonable effective income tax rate? (Please do not confuse effective and nominal tax rates!) In my view: "All in" should be about 50-55%. When I say "all in" I mean absolutely everything -- federal, state, local, national pension, national health (if applicable), yada yada yada. That would mean top 1% still have net income (after taxes) of more than 200K USD.
If you look at highly developed economies, it seems hard to provide a healthy social safety net without 50% effective income tax rate on top 1%.
In Hongkong, the top effective tax rate is about 15%. The social safety net is appalling. The number of poor, working, elderly people (collecting cardboard in the street to sell by the kilo to recyclers) is heartbreaking. You would not use the public health system, nor the public school system; nor depend upon the national pension, nor unemployment benefits. One bright spot: The public housing system has served well the working class and below. (I joke that 15% only gets you a good metro system and airport.) Hongkong feels like a semi-feudalistic society.
