Another problem is lack of accountablity. Look at the situation in DC (DC Teachers union leaders are accused of using union funds for personal items--furs, art, wigs--to the tune of $2 million). When the teachers are frustrated, who do they have to turn to? What kind of support do they get? What kind of support do parents get? The kids get the least support, IMO. Everyone wants them to produce better test scores (never mind grades) with less money for books, supplies, etc.
