Inequality of the tax system

Ok, I saw tonight that Romney paid about 15% of his income in federal taxes.  Since Romney made millions in 2010, and paid only 15%, then I should have paid nothing.  My income was well below $100,000 and I paid 13% of my income to federal income tax and my income was retirement!  And now Mitt wants to buy the White House so he can make it even easier for his rich friends to dodge taxes.  He and all his rich friends are the true welfare class.  They take many times more than they give.  Yep.  Welfare is alive and well in the good ole USofA.  And the face of welfare is wearing $3000 suits and shoes, driving new expensive cars.  Were it me, I would be ashamed to ask the American taxpayer to vote for me.  It is the height of arrogance for someone who cheats the taxpayer at every turn to expect them to vote for their welfare antics.  But vote they will.  Americans are so stupid.
