I don't think the US was every a free market capitalist country... It's probably hard to swallow for a lot of people from the US but the government often interferes with monetary policy and other areas it wouldn't if it were fully free market capitalist such as regulations from the fda.

Every country in history has either had a socialist system or an imperialisation with one monarchy in the total power...

The socialist policies you're gaining now are more a natural development, it's probably a standard flow into how Europe and other old areas are around now...
