I think it's a definite possibility, given how most of the "social studies" departments in all levels of education are exclusively populated by leftists. As you read this article by Michael Beran, bear in mind that John Dewey was a humanist who signed the Humanist Manifesto. Anyone who studied education in the United States knows that he is rightly considered to be the "father of modern education". That's NOT a compliment! By and large, the poor kids in public schools are being taught to be unquestioningly subservient to the progressives in big government. A good number escape the stupefying influences, owing to decent family life and Christianity being taught in the home, but they face incredible odds at school.
Many of my friends home-school their children. I salute their commitment to the upbringing of their children.
