I'm afraid that the kids I've known who get used to a spanking begin (unless it comes close to brutality or sadism - and there's that, too) to view it as a sport to be had with their parents. Certainly a lot of kids I went to school with got slapped enough times at home, but found 'driving Mum mad' quite funny. What they DIDN'T get - and which I did - was having privileges taken away. The family would have a shouting match, Dad would bash the kid two or three times, the kid would bawl and snivel, then they'd all go out to the cinema and the kid got a Coke and sweets. A few days later, the kid would annoy his parents enough for a similar scenario to take place - but he'd never have his (say) Boy Scouts outing, free time with friends, or riding lesson denied, or lose his pocket money. I just don't see that method teaching 'action and reaction' or 'action and consequences' very effectively.
Children need to feel confident of being loved, and being secure, that whatever happens, Mum (and hopefully a Dad, too) will always love them - and early on they need it expressed in tactile ways - hugs, tickling, all kinds of daft games and giggles, being tucked up safely in bed and being given a goodnight kiss. I know parents who fall asleep on their sofas watching television and don't even put their kids to bed properly, let alone give them random little hugs and squeezes and tell them how smashing they are. Eventually, the desperate need for attention - since any attention (i.e. a validation of your existence) is better than none - can go very sour, and the child ends up in all kinds of bad situations.
I don't say that's what's happened in all these cases, because kids are mostly herd animals, led by the Alpha Child, but enough bad behaviour can be laid not just at the feet of parents, but at those of distant, disengaged, self-centred, cold, nagging, undemonstrative and unloving ones. Those who look upon their 'gifts from God' as annoying obstacles to watching telly, going to the pub/club/shops, or chatting endlessly on their bloody mobiles.
