All I am saying its there money to do what they want with it. If its my money I don't plan on sharing. I don't believe that I should have to give up any more money than the man that makes less than me. If you pay 10% than I pay 10% doesn't matter what are are annual income is. If you take 30% from me and only 10% from you then that ain't fair.
So, as a policy maker...
Let's say you have some foreign, heavy-hitter of a company express interest into bringing their business to the USA....
... now this is a company that, regardless of how they are taxed, will bring SERIOUS revenue to the U.S. in the form of jobs and the trickle down effect thereof...
As a policy maker...
You now have a decision to make... Either, you can look at prospective "company X" and say, "please come to America to do business, where everyone is taxed the same... 30%." .... at which point, "company X" says "F#CK you. We'll set up shop in Mexico then."
... in other words... tax breaks are sometimes a necessity to bring in big business that, otherwise, would do their business elsewhere.
