Communists quietly infected our nation's schools long before 1968. Bill Ayers is where he is today due to the mentoring of the Marxists of my father and grandparents’ generations ( born 1913 and early 1890s)
Compulsory K-12 single-payer and socialist-entitlement schooling was a Prog idea of the early 1800s.
Progs have always controlled teacher training and curriculum development.
Progs have always pushed for greater and greater secularization.
Progs have always pushed at the edges of society's moral and ethics.
The very idea of single-payer and socialist-entitlement schooling is an abomination.
Finally....In a generation or two our citizens will be pining for the good old days of Obamacare when it wasn't so bad. Every argument that is used for and against government schooling will be used with single-payer and socialist-entitlement health care.
Sadly, I fear you are right.
