I know that this isn't true for at least Social Security. The original promise was that it would be purely voluntary. It was later rolled out to be mandatory. It has also turned in to a stack of IOUs.
Obamacare was a stack of lies (prices didn't stay the same, quality and access to care decreased, providers could not be kept). It also is a money pit.
I also know that despite our awful implementations of social programs no other economy in the world currently rivals that of the US. Even in poor economic conditions. The poorest of the poor in this country is in magnitude better conditions than their companions in other countries. I'm don't want my country weighed down any more, the way most others are.
