Parents don't bother keeping up a PTO in their kids' schools. Parents can't be bothered to make sure homework is done, much less help their kids with it. Parents dress their kids like strippers and gangstas and wonder why kids act out. Parents don't teach respect. Yet, when Johnny can't read or acts out Columbine II, it's the school's fault.
There is some truth to that however the majority of parents do keep up with their kids, dress their kids correctly, teach respect, etc.
Did you watch Stossel's report on 20/20? I highly recommend it - "Educrats" are the problem.
