But my larger point is that I think "free market" eras also correspond with worse quality of life for the majority of citizens. I'm thinking things like pre-safety-regulations industrialization in the US; the environmental catastrophe that was the 60s (so bad that it led Nixon to create the EPA); the affordable housing catastrophe that has been the past 15 years.
We can obviously produce more if we don't have to worry about externalities like "worker safety", "being able to afford rent", or "habitable environments". Free markets create conditions where externalities aren't as important.
