What you don't seem to grasp is Romney already paid income tax on his income, and then invested from what was left over until he got to the point he could live on investments that are taxed at 15%. The same as hundreds of thousands have done, are doing, will do. It's an avenue that's available to every American who invests money, is 100% legal, no slight of hand needed. Sure he has more than most, but he's sharper than most too. Yeah, I know most Americans won't ever have the money he has, but if you have $100k in savings, you could invest in municipal bonds and pay no tax at all. Or $1000 and no taxes. You have an insatiable hatred of the wealthy for some reason. Some may deserve it but if your vitriol is only because they have more than you then how sad you truly are. There is no perfect economic system but under capitalism those who produce tend to do better. There is no bizarro world where everyone lives wonderful lives with all they desire without much effort.
Name the corporate welfare and most likely it's incentives available that allow companies to grow and add employees and produce more in tax revenue. Are there incentives that need to be done away with? Yeah, most likely, such as farm subsidies. By the way most incentives given to the oil industry target wildcatters who explore for new sources of oil. But whether corporations get incentives or not(and incentives are usually tax breaks) saying it's ok to pay out trillions to people in money we have to borrow and pay interest on because the government gives breaks to evil corporations is ludicrous. Do you not get we're broke and getting further underwater by the minute?
And it's not just minorities although that's where you want to put the focus. 99 weeks unemployment, record numbers on food stamps and disability, propping up teachers unions and other public sector unions(so they'll keep getting votes and campaign donations), subsidizing companies that were big campaign donors, the list is endless when you are throwing around hundreds of billions at a time. What he should be doing is making it possible for businesses to succeed without tax and regulatory anchors keeping them from growing and hiring. Putting people to work instead of paying them to sit at home is the surest way to increase tax revenue. But why work if Uncle Osama will send you a check?
