And I don't think the confiscation of gold from Americans can be repeated at this point. In 1933 America and Americans had most of the world's gold, and gold had been officially recognized as the only true money for 60+ years by Britain and America. (Not even silver was considered money.) Americans still had a lot of trust in the government.
Under these conditions, it made sense for the elites to try financial repression (legally forcing Americans to turn in their gold for the previous fixed price of $20+ per ounce) as a major support for their system. The reality is almost the exact opposite today, so I don't think they will try that trick again.
