Yeah I haven't heard anyone suggest a flat tax in conjunction, but social security and unemployment could be eliminated, food stamps cut sharply, Pell grants all but eliminated, and so on. I'd conservatively estimate that a trillion of the $2.8 trillion cost could be offset through reduced social spending elsewhere. Another $600B or so would come back to the government in the form of income taxes. So net you are looking at $1.2T. No question, that's a lot of money but it's not far off from the size of the MIC. It's a choice that could be made.
