Switzerland is an okay counter-example I'd say, Singapore not as much since their 'guest workers' aren't real immigrants and get NONE of the social benefits/housing that Singaporeans get. Very very few people become proper immigrants (full residents) to Singapore.

The real problem with both Switzerland and Singapore examples though, they're small tax havens full of rich people.

Kind of like Monaco...which surprise...is actually 70% immigrants!

But when the counter examples are Singapore, Switzerland and Monaco...I think we both have to be honest and look at what we're actually measuring ("the global super rich are higher trust regardless of country of origin").

Finding exceptions doesn't disprove the correlation.
