I personally don't believe anyone should pay a larger percentage in taxes than ANYONE else. That is why a flat tax is what I would ultimately want; however, it will never happen because all the people at the IRS would have to be dumped out on the streets. I haven't had a job yet this year and am looking at the possibility of going down the tubes - again - but I don't begrudge wealthy successful people the right to keep the same percentage of their income as I will keep when I am flipping burgers and asking if you want frys with that.
Historically there always has been a class of wealthy individuals and a class of those with virtually nothing. This isn’t going to change for a variety of sociological reasons; however, the rise of the middle class and subsequent rise of the poorer class is a direct result of the wealthier class making more money. A poor person in this country would be considered wealthy in other parts of the world. This is because of capitalism and a tax structure which (at times) allows for rapid and sustained growth because of the availability of capital through investment, savings and even spending by the wealthy.
There has to be an ongoing growing pool of investment capital for a business to borrow and grow. This comes from the savings and investments of the wealthy class. A flat tax is the only truly equitable solution which will allow economic growth. Otherwise we might just as well redistribute the wealth as the Communists advocate.
