It’s a little more complicated than that. One can definitely make a comfortable living in Singapore (great tax rates, financial hub) but one of the key cultural aspects is that Singapore is asian (or to be specific, Chinese) dominant. Glass ceilings and hidden racism do still exist even if much progress has been made in the past decades.

And of course, one cannot forget that the food in Asia is much better than the US (I may be biased though)
