If you don't understand my point, just say so. But to make silly excuses for incompetence of curricula and personnel is not helpful.
If the points you make were relevant, we'd have had these educational problems since before the founding of this nation.They are much more recent than that.
Teachers have minor or no problem with the curriculum these days the state and feds dictate it. Most people did not go to school or went to one that is much different at the time of the founding of this country.
SO maybe I don't get your point, enlighten me.
