Your rant makes zero sense.
I'll play your game.
Here is the 2010 breakdown of Federal Taxes collected.
41% Is individual Federal Income Tax
40% Is payroll taxes (15.3% in which half your employer pays and the other is shown as FICA on your check)
9% Is corporate income taxes
6% Is other
3% Is excise taxes
1% Is estate/gift
Using the citations I gave you already lets agree/disagree on a few things:
1) Corporations technically are not people but for some reason are treated as such, at least for some issues.
2) Everyone pays on FICA up to 127.2k AGI currently. This point is moot.
3) The 4th and 5th 20% of the US population actually has a net negative tax return (they receive a return)
4) It is more likely than not these same individuals will not have to worry about any estate or gift taxes.
If we reduce the rant of yours to the 41% slice and pretend that some of these individuals don't own said corporations or pay any estate taxes than my argument diminishes into the top 2/5th's of US Taxpayers pay 35.67% of the total FEDERAL taxes, while the bottom 3/5th's pay 5.33%.
It's still lopsided and repugnant to ask them to pay more.
