I'm curious how you explain Japan. Their traditional religions have never been very big on moral instruction, certainly not the way Christianity is, and today a supermajority of the population doesn't take religion seriously at all. And yet you have a generally well-behaved populace, low crime, very low rates of out-of-wedlock births, and so on. They have their own problems, of course, but not so much these particular problems.

I guess you could argue that a particular self-reinforcing system of social norms could be considered a sort of orthopractic religion, but that would be a bit of a definitional stretch.
