Tax structure is beside the point of the challange that you made.
Must I remind you that you asked:
...but the fact remains the rich benefit more from the society, they SHOULD pay more.
I have heard this here a dozen times. But whenever I ask anybody to actually quantify and track how a millionaire gets many times more paid "benefits" from "society" than someone who makes $25,000 a year, people dive out the windows.
I "actually quantified" the benefit. I proved that having more means you benefit more. I did it in a demonstrated dollar benefit.
