If discipline at home created obedient citizen slaves, the "state" would be all for it. As it is, parents are threatened not just for spanking but any form discipline. My wife and I got threatened by a school teacher once for making our son read too much during the school year. She said it was "abusive". As a parent I say to the state, Stay out of my business, I'm doing the best I can with what I know.
As it is, it looks to me like the state is trying to raise a generation of undisciplined kids that cannot read, write, or hold down a job. I think its easier to enslave them that way.
