State and Federal meddlers have ruined teaching with their idiotic testing demands. Couple that with blaming teachers for most of the academic shortcomings in schools. Add to that the insidious infestation of Political Timidity (formerly Political Correctness) into the classroom and the willingness to excuse poor student behavior on societal issues....no wonder people do not want to subject themselves to public humiliation and criticism for modest pay and go to essay-have
. Pretty simple to understand.
