For a lot of Asian countries the “asian dream” is still somewhat realistic.

Just look at China or Korea. Many of the older folks there grew up in abject poverty, but the countries managed to develop themselves through hard labor into modern, wealthy nations. The promise of “my kids will have it better” was actually true for them. And that promise still drives a lot of the work culture. In China the first cracks already appear, since for the first time in 50 years or so, the current youth has no way up anymore.
