On the one hand, studies have suggested that nearly half of highly successful entrepreneurs/founders in the US are immigrants or children of immigrants. As the US becomes more authoritarian and more corrupt, its easy to imagine people choosing to do their new startup from, say, Berlin.
On the other hand, lots of people choose Singapore, too; rule-of-law-based country with relatively easy access to capital and relatively low taxes — but without actual democracy.
I'm aware of my own inherent bias of wanting democracy to be important to people when making this kind of calculation, but I'm not sure that we have any real evidence of that.
