“Thanx this is the first time in my decades of reading I have seen someone posit that free public education in the US sprang from communism.”
No teacher would teach that or admit it. Communism has a stigma associated with it, and this is somewhat true with socialism.
The USSR (Soviet Russia) and NDSAP (Nazis) have socialist in the name. DDR (East Germany) has democratic in the name.
The Marxism/Communism/Socialism/Progressiveism that schoolchildren are brainwashed with is labeled democracy.
Its like putting a flavor in medicine to make it easier to swallow.
