If they are local, they may not want to go abroad. The mindset here is that you begin to accumulate large amount of cash savings early in life (20s-30s), which is a huge boon. This gives you a number of benefits compared to your peers in less hot industries: you can buy an apartment and save on rent long term; you can start your own business; you sleep better not worrying about the future; you can negotiate better work conditions because you are not afraid you'll lose a job.

The fact that you would not have the same position abroad (i.e. your cash savings are large locally but small if you lived in a rich country) is not a loss of any kind, it's just a fact that has no bearing on daily life.
