>So perhaps one should look to the behaviour of the parents and society in general in order to tackle this kind of misbehaviour by ensuring that it does not happen instead of simply reacting to it when it does.

Ok tell us how since you seem to be an expert on it. You can't "tackle" every situation with sweet words before it happens, especially when you're directing those words towards a being that doesn't have a full formed brain yet.

My general experience with Europeans is that it takes almost until middle age to leave the house, stop suckling their parents income, and act like adults where they can be responsible for themselves.

If that's what you want for your country fine but I think the hands off parenting and letting them get away with everything when they're young has consequences.

Anecdotally, my wife's German cousin came to visit quite often when he was little. His parents never disciplined him and took the Euro approach to essentially whining at him when he did something wrong. When he got upset he would just go around American Grandma's house knocking her stuff off the shelves and breaking it. Grandma had enough of that and gave him a nice swat eventually. He neever did it again. The kid is in his late 20s now, doesn't have a job, his parents are buying him an apartment, he has no clue what he wants to do, and has failed out of school multiple times. He also still acts like he's 15.
