That doesn't make any sense to me. If a person makes $15,000 from a minimum wage job, just how much money do you think you could get from them, while leaving enough for expenses?
I didn't expect it to make sense to you, but why would I need to convince you? I'm an American and I have a point of view. The validity of my view is not measured by whether or not I convince you. You are one person just like I am and your opinion carries no more weight than mind does. At least that was the way our Country was supposed to work.
In my opinion, everyone should pay the same amount in taxes irrespective of income. Anything else is unfair. To claim that the rich aren't paying their "fair share" while 47% of the people pay no federal taxes at all is an absurd perversion of the word "fair". That is my opinion and I have no need to convince you.
