Singapore

I can’t speak to the “best in the world” because I don’t know about the whole world, but the place I work for is located in 145 countries and the US by far makes the most. I am at the bottom of the pay scale (low cost of living city & haven’t worked here long) & I make over double what someone 2 levels above me (5+ years more experience) would make in London.

Similarly, I know someone who lived in Japan and made $30K USD who moved to the US and went to $150K USD doing the same job.
