I think that being the first rich, advanced large country that isn't western is the reason. On paper, they have a similar relationship with money, technology, their religion and traditional culture. I can't explain the strangeness away with those differences.
When I read something like this about some trend or supposed cultural pathology cropping up, I have nothing to connect it to. I don't intuitively get where its coming from or why. Not even a hint. I don't know whether to dismiss it as conservatives concerned with something harmless, some fringe phenomenon or whatever.
