Unions promote mediocricy. If thats fine - good. Europe can allow themselves to be mediocre, while most of inovation is done in United States of America. But what if USA would do the same, where we would get inovation? China?
This is a pretty baseless claim - do you have any evidence that most innovation is done the US because of an absence of unions, or despite an absence of unions?
And why tf would you think innovation is the only driver in well-being of a society? How about something like this? https://en.wikipedia.org/wiki/Human_Development_Index
