Obama talks about helping small areas in the US with lots of poverty, but part of the "help" is cutting taxes for business.

Once a tax cut gets applied to a part of the US, businesses will push to spread it to more parts. Then businesses elsewhere say that "fairness" means they should get a tax cut too. Eventually it spreads into a general tax cut for business.

Business pays too little taxes in general. If we want to put specific zones at an advantage, let's raise taxes for business everywhere except those zones.
