Sounds like somebody's PO'ed that the best he can be under capitalism is a schoolteacher.
Got that right, D.P.! He can't believe that all of his really stupid friends drive New BMWs while he's schleping around in a rust-eaten, cock-eyed, barely running Chevy Cavalier(I love Chevys, but that car was a POS). So, he directs his disappointment through his anger, and releases it on the kids. I don't think many of them will buy it because Mr. Bennish sounds like a creep. He also possesses a nice, high whiny voice, don't you think?
Loser.
....and or that his coke supply is drying up and it's Bushs fault.
