> Japan has much less criminality than NL
Seems that depends on where you look but it's at least on par or below, so point taken.
In Singapore it seems to work well as well. But I always assumed because it is so tiny they will always get you and you will get punished.
It is interesting to learn more and it is a difficult issue which probably is partly unsolvable, I show one perspective, but that might not work elsewhere. I just do not see the damaging a young person from taking part in society forever is a good plan, at all, for small infractions without bodily harm.
> and the subsequent social downgrade.
By no means I claim to know much about Japan but from what I know from reading/watching a lot about it I would wager it's more this than the punishment... But it would need research I guess to figure out why the differences.
