Most of our tax money (70%) goes for social programs, especially Medicare, Medicaid, VA, and Social Security. Some conservatives don’t like Social Security and Medicare called an “entitlement,” but they truly are—we should be entitled to what we paid in with interest. (I’m not because I have a teacher’s pension and get nothing for what I paid in to SS in non-government jobs, nor a spousal benefit.) And it isn't the fault of Obama, as some detractors claim (he's got more than enough problems without giving him that one.) That will only increase.
The defense budget is extremely small, although the sequestration was Obama's idea (now trying to blame GOP) and is a rather small amount, it will certainly hurt the thousands of civilian employees right now as other lower paid jobs become unavailable because of raising the minimum wage—which always hurts the economy. It's a wonderful 2-fer for the president to hurt the economy even more which seems to be his major desire as he flits from gay marriage to stomping out freedom of religion to passing out free contraceptives instead of freeing up businesses to create more wealth.
The federal government should have stayed out of education--it wastes a lot of that money, and that responsibility was left to the states. Head Start, one of the biggest federal wastes with a 40 year history of failure, will probably get money better spent on bridges and roads, that he never gets around to that despite his promises. http://blog.heritage.org/2012/09/23/chart-of-the-week-70-of-spending-goes-to-dependence-programs/
