A Singapore-style regime wouldn't work here. People are too rebellious and dislike conformity. You can't just impose rules on people and expect them to like it. People may follow the rules if there are few of them, and people make them themselves, but you won't get the kind of enthusiastic obedience that trational East Asian societies have commanded. You have to be satisfied with minimal obedience and minimal social cohesion or find ways of sugarcoating the pill of compliance.
I suppose that European societies do survive with little religious faith and have done so for at least a generation, but whether they'll endure over the long haul is another question.

But the vitality, resilience, and energy of Western Europe do look diminished or impaired.
