Teachers, by and large, are the laziest, dumbest people you'll ever meet. It takes a 4th grade education to teach 3rd grade. For most of their lives, they are the smartest person in the room, and it goes to their head. It doesn't take a BA to teach, the college and certification are a cash cow for colleges. At the end of the day, students are just a commodity.

Their children (Boomers) grew up in an age of plenty/excess and they seem to think that that party has never ended. Their children were the Hippies. Their children were Yuppies. Etc. People suck. Every generation has had it's share of bums, losers, commies, creeps, and what-evers living off the work of their betters.
