He WILL increase their welfare payments, and that will make them happy.

However the great majority of Black people have jobs. It's just that they aren't nearly as high-paying as what they'd like. They want their jobs to be higher remunerative. That is what they're expecting from Obama. Judging from their comments, apparently many of them expect great jobs and more pay to automatically come their way, without any undue effort on their part, thanks to The Grand Distributor. When that doesn't happen, what then?
