Gold was only confiscated from people who refused to obey the law that they had to SELL their gold to the government. Almost everybody did, and they were compensated. The cases of confiscation were much like criminal cases now that use asset forfeiture for stock market manipulation or drug dealing.

FDR was far from a socialist. In fact, almost every economist says he saved capitalism.
