This does not dispute the central point of the quoted piece, which is that the quality of life of most Americans is very poor contrast to that of the average person in some subset of European countries. I would wager that most coffee shop employees are more concerned with labor protections, healthcare, social welfare, the ability to afford housing and take vacations than whether their country’s economy is producing “innovative companies” (read: tech startups?). This was certainly true of myself when I worked in food service.
Even so, this point does not stand well on its own. It may be that Europeans are deincentivized from creating enormously overvalued startups because their quality of life is much better (although I question whether this is worth bragging about, from a US standpoint). Nevertheless, I’d consider things like lack of a single market, fragmented languages and cultures, completely different VC environment, and so on to be much more impactful in that regard.
