It’s hard to know where change leads.
The twenties broke new ground in what was acceptable culturally, women’s voting, urban overtook rural, cigarette smoking, fashion, etc. The freed up social norms regressed somewhat during the Depression, with weed becoming illegal and the attempt at Prohibition failing. All this gave us the buttoned-down fifties.
The sixties broke ground again with the sexual revolution, ascendance of leftism in academe and women’s lib.
I’d have to say the twenties left us better off while the sixties pushed us irretrievably left, to great disadvantage.
From the 20’s onward we were pushed to the left. That wasn’t “freed up” social norms. That was the start of making women unhappy with their roles as wives and mother’s. FDR was a champ at socialism.
