I can't help but think that these "educators" are themselves products of the same degraded system that they're now administering to their pupils.
It actually goes back to John Dewey, in the early 1900s, who intended to turn America into a socialist nation via education. His work infiltrated all the colleges of education beginning with Columbia. The early 1920s was when they began to change the way children are taught to read by deemphasizing phonics. By the 60s enough teachers had been trained to begin their real socialist work.
They did all their experimentation in the inner city schools because inner city parents don't complain like suburban parents do. But now the suburban schools are getting the programs that were "practiced" on the inner city kids. That is how we got Common Core. Teaching kids without really teaching them so they end up as adults who cannot think to save their lives.
I knew of this before any of my children were old enough to go to school. None of my kids went to public school. I either paid for private/parochial school or I homeschooled. Any school my kids went to I made sure the teachers had the same ideas of education as I did. My kids can think. All of them went to college and none of them are politically stupid. Amen and Amen.
