When I was a kid, we could earn some sweet-money digging snow off a neighbour's path or washing a car. My father hated washing his car and was happy to pay us to do it. We'd never think of expecting money for feeding the dog or changing the sandpaper in the (despicably vicious) budgie's cage. They were our pets too, and if we wanted to keep them, we had to take responsibility for them.
Nor would we have imagined that we could be paid for being polite and demonstrating good manners. In those days, adults had a cheaper option available which was applied if we were bad-mannered or rude. It worked exceptionally well.
Discipline is no longer permitted. So parents are turning instead to bribery. Kids can now earn money for far more than washing the car or clearing snow or leaves. They expect to be paid for being nice to people.
That is not a good idea. Children operate a simple, logical approach to the world. Touch something hot, don't touch it again. Get a reward for doing something, do it again. The trouble comes when they associate things like good manners with a reward. If you stop the reward at any point, they see no reason to continue. It's a deal, of sorts. A market bargain. If companies stopped paying me for research I'd stop doing it. If I did something for a company and they didn't pay up, I wouldn't accept any further work instructions from them.
So it is with bribing children to be good. There is no punishment for behaving like mini-anarchists and doing what the hell they please, so the only reason they have to not do as they please is that someone is paying them to follow the rules.
Stop paying, and they stop taking instructions. That was the deal so if the money stops, the deal's off.
The market is ingrained in biology. Even chimps have been shown to make deals and to get frustrated if they feel cheated. It's not evil. It's normal. People get on with one another by coming to mutually agreeable arrangements. All government needs do is make sure they behave themselves in the process, and provide a legal system so people can get redress when shafted and con-men can be punished.
Note the difference. Children are now being brought up to believe they can do just as they please. If adults want them to behave according to a set of rules, they have to pay them. Yet when these children become adults they will find that it works the other way round. There's no reward for following the rules. Instead there are punishments for not following the rules.
So this 'no punishment for bad, reward for good' approach to child rearing is the exact opposite of what the child needs to know about the adult world. Both involve deals between individuals but in the child's world, there is no punishment for breaking the deal other than a temporary withdrawal of sweet money.
In the adult world, punishment can involve losing your job, your home, your freedom.
It's going to come as something of a shock.
UPDATE: That was quick.
