It’s always been like that, hasn’t it? I seem to recall it being one of the reasons why liberalism has had such staying power.

It was how the Dutch became a powerhouse on the line of Spain, England and France in the colonial age. Because they let their people be, and didn’t take their wealth, it became an attractive haven for rich families who then did business.

I’m not sure the latter is as beneficial as it was then, as you can now turn money into more money without investing in local business, but the former is going to remain true forever. People who have the means to do so, will always chose the freer country.
