IMHO That's the spontaneous action and unless curated carefully it happens everywhere. It's the spontaneous way because all the bad things about the Western culture are about getting rich or happy quick. I'm sure the outer civilizations also desire to get rich or happy quick and that's why they end up trying when exposed to the Western ways but unlike those cultures the west is very good at oiling the machine to run very productively. Maybe its something about being an industrialized high throughput individualistic culture, I don't know.
