Gary, Another view on how much just the federal government spends on welfare:

"(T)he Senate Budget Committee requested from the nonpartisan Congressional Research Service (CRS) an overview of cumulative means-tested federal welfare spending in the United States in the most recent year for which data is available (fiscal year 2011).  The results are staggering. CRS identified 83 overlapping federal welfare programs that together represented the single largest budget item in 2011—more than the nation spends on Social Security, Medicare, or national defense. The total amount spent on these 80-plus federal welfare programs amounts to roughly $1.03 trillion."
