and the state doesn't like that.
in 1970,the US government was commissioned to investigate and report on the civil upheaval of the 60's.in 1974 (iirc) one of the commissions (the tri-lateral commission,which was considered "liberal") concluded that the reasons for the civil unrest of the 60's,and I quote "was due to an excess of both democracy and education".
by 1978,the entire board of education curriculum had been totally revamped.
now I am not trying to speculate that the US government purposely changed an entire k-12 curriculum in order to better indoctrinate American children to be more docile and complicit to the powers and authority of government institutions.
naw..I am lying.that is exactly what I am saying.
