I would LOVE to see a chart comparing America today to America pre-1900. I would bet that all of the BS going on during the turn of the century negatively affected America.
America has been on the decline for almost 100 years now, ever since the socialists started screwing it up back under Wilson in the 1920’s.
It's just that the decline was masked by WW2 and the prosperity that followed because we were the only remaining country in the world with an intact manufacturing sector.
