Nonsense as Sweden has more per capita billionaires than US and more unicorn startups per capita than most US cities
As for startups, it would be better to see the success ratio (how many people tried to create a startup vs how many succeed) and not just the number of survivors.
Who made this claim? Certainly not me. I claimed that, for an ordinary software engineer (i.e. not a startup founder), life will be better/easier in many other European countries.
