The greatest moments of the usa was perhaps in the 1820s under Andrew jackson...whonwas a genuine threat to the liberal elite and inspired many genuine positive cultural and policy changes for the white race...
Or perhaps under Ted Roosevelt who embraced fascist economics and inspired a culture of unrivaled innovation in the usa.
The 1950s were fine I gues...from a prosperity standpoint...but that is because of accidents of history and happened despite the cultural zeitgeist...not because of it.
