Wait....just to be clear.......you said the bottom 50% ALSO pay payroll taxes as well?
So in other words, you have no idea what payroll taxes are.
Lesson 1.......employees do not pay payroll taxes. Never. Ever. Employers do and it has no affect on the employees paycheck. It is a tax match to add to the employees FICA. Quick....google FICA so you know what I am talking about.
Lesson 2......when the top 1% make their large incomes and capital gains as you claim....they pay 1040 personal income taxes on that income. I know. It sounds complicated.....but you can not avid a 1098 submitted by your portfolio manager as a course of LAW.
Lesson 3.....all pay SALT based on their income. Rich, poor, priveleaged, of color......we all pay SALT.
