The college we all went to accepts about eight percent of applicants. Sometimes, as a teacher, I come across students who fit the eight-percent profile thanks to their intellectual curiosity, hard work, intelligence, and discipline. Take one of these qualities out, and they’re bound for a less-selective college.Now, I understand the so-called Frankfurt School that has since the late 1940s infiltrated its ultra-left professors into American colleges and universities and promulgated Marxist teachings among young Americans. I understand it well not so much because I’ve studied it but because I was its target.The way indoctrination in American higher education works is subtle. One never sees huge red banners with blatant propaganda slogans that I saw growing up in the Soviet Union. No, the noble ideas of equality and equity fascinate young American minds through logic. And logical it is to yearn for a more just world with less envy and strife.
