The point, and there was one,
Is that the deficits, particularly as entitlements move into the future, are driven mostly by social spending.
Entitlements for 2010 are at about $1.5 trillion. If you eliminated the Department of Education, the Department of the Interior, and the entire Department of Health and Human Services, you would save about a tenth of that amount. Not counting defense at $673 billion, every single thing the Federal govenment does other than entitlements comes to about $700 billion.
This doesn't even count discretionary social spending.
