what do I see as reasonable taxation ?
I see as "reasonable" is the amount that is left after paying taxes.
So, for some , with small income, it should be 90% left ( 10% tax), for some - 60%, and for some - 10%.
If some executive makes $100 million per year, even at 90% taxes this family will have lots more left than most of us.
I think executive compensation ( specifically - bonuses) should be tied to salaries of their employees ( like in Germany) , then you would not have disgusting situations when Aetna CEO was telling Congress she made some obscene amounts of money and medical payments of her company were called "loss".
