What if some turn of century POD causes Progressivism / Pragmatism to never catch hold / lose all popularity in the US. Nothing replaces them per se, but they are discredited in popular & elite imaginations.
I wonder what the impacts would be.
Within the US, from 1900-1934, some guesses can be made:
Teddy Roosevelt, Woodrow Wilson, Herbert Hoover, FDR - none are elected president, or reach high office (at least, not in a recognizable fashion) as their core belief structure is repudiated.
No prohibition (temperance & progressivism were closely tied) => no war on drugs?, weaker/poorer mafia (no ready made smuggling market), poorer Kennedys (no smuggling money).
No WW1 (No WWilson pretty much ensures this?)
No Palmer raids or wartime socialism (progressivism justified these, with out it...)
No Panama canal (no teddy) and less early 1900 interventionism.
No wartime socialism => stronger free speech rights.
No teddy => no/less trust busting => longer robber baron age => more intense industrialization, higher economic base
No teddy => no/less national parks
Idea of anti-americanism as internal political charge (created/manipulated by CPI during WW1) doesn't become virulent McCarthy fodder?
Fewer/different dams/highways in US?
No Empire State building?
Smaller US military?
No presidential fitness medals?
Dramatically smaller/different federal government?
Less imperialism/interventionism=> more isolationism => earlier phillipines independence? => ??? no war w/ Japan?
Smaller fed gov=> lower taxes?, smaller military?
Apart from the obvious (no panama, no / later panama canal, earlier phillipine indep, no WW1 involvement) does the change to US internal politics/policies have an appreciable impact on the rest of the world? After all, at the start of this time period, we had substantial growth and inventions, but minimal world presence.
