The problem is you are thinking about a guy working for someone and that is his salary. The problem is small businesses, even the smallest mom and pop, gross more than 250k and those are the ones they are going to raise the taxes on. The corporations can handle them small buisness can not. If you are grossing 250k but have operation cost of 220k then you will not be in buisness long. The tax hikes Obama is talking about will not close the divide between incomes, but rather enlarge it. They will drive small buisness out and consolidate that income in the corporations. When that is accomplished the Governement can "regulate" those companies much easier and pervasivley, effectively nationalizing them.
Don't believe me? 1. read the histories (both past and current) of socialist regimes and 2. take a look at the bailouts, reforms, over sight, and regulatory measures being implimented as we speak. It is not coinscidence. These "words" sound good in a speach but are they way the federal government takes control.
