The problem is religion. That's why there's too many people (birth control is evil and God doesn't want it, etc.), and that's why they have a lazy culture.
What is a "lazy culture"? It sounds like there is a one true way of living: working yourself to death, for what? To have a bigger number on your bank account than your neighbours? To have a faster car to be stuck in a traffic jam on the way to office where you will do meaningless work for 60-80 hours a week? This not a proper way to live life in my opinion.
