they were the ones beating the "FDR is a Commie" drum when he created Social Security, etc.
FDR was a Commie, though. We only see Social Security seven or eight decades after the fact, but the FDR administration completely overhauled the nation's economy, especially the agricultural sector, placing enormous swaths under extensive government control, with explicit production targets and price targets. The administration actively disbelieved in competition and a free market, and thought it could restore the nation to prosperity by paying people to fallow their land and by burning crops. By "disbelieved in a free market", I don't mean that they had a bunch of Regulators out there keeping Rich and Powerful People from doing Bad Things. I mean that they kept the Rich and Powerful People in business because they were rich and powerful friends of the FDR administration, and they did a lot to help them.
The FDR administration's interventions are a primary reason that the Great Depression was so Great. Fortunately, most of them were disassembled after World War II, resulting in an impressive game of catch-up as the nation returned to economic growth and prosperity (and unfortunately convincing some people that war is an economic catalyst instead of an exercise in spending valuable effort blowing stuff up, including some of the most economically valuable stuff out there, human lives).
Anyway. If you hate Big Agriculture, factory farms, and crop monocultures, then you should despise FDR, who erected the system which brought them upon us.
As for the rest, Social Security was the icing on the cake. It's an out-and-out wealth transfer in a way that the other programs, but at least it's an honest wealth transfer -- a generational wealth transfer, and future generations are likely to be richer. It makes a ton of economic sense as a transfer program (by tying your retirement pay to actually working it avoids the worst negative incentives of transfer programs, among other things). You just need to make sure the demographics and economic growth work out relative to the benefits -- easily doable. From an economic standpoint, it's wildly superior to the current health-care reform effort, which... let's just say it hasn't been a wild success at delivering its headline promise of cheaper health care for all.
