When my son got to the end of the high school there was not a singleteacher left who taught him in the 9th grade. Why? Because all of themwhere "let go" for one reason: keep the labor cost low!! No one caredabout quality.
yes, and it's exactly because the teachers are not hired/promoted based on merits, but on tenure/seniority, etc..and who is responsible for that??? the unions??
