You mean "it's good that EU will never be a tech powerhouse"? Or you mean "it's good for France to tax large tech companies for internet traffic"?
It's not obvious that housing "tech powerhouses" is a good thing. I mean look at the US, and how much problems all these companies bring to society. I'm also not sure we'd want anything like that in Europe or EU, if we also need to accept the same consequences as the US did.
American billionaires are self-made (70% became billionaires during their life) where in Europe 70% inherited it. The powerhouse companies of the European economy are stagnant and the families which held them 100 years ago have a great chance of still holding them.
Are tech billionaires obnoxious? Yes, undoubtedly. I'd take them in a heartbeat over having a more permanent aristocracy.
Given the class inequality differences between the two places, and how one seems to basically be "survival of the fittest, if "the fittest" is ~1K people", arguably "tech billionaires" seems way worse than "a dying aristocracy", but maybe I'm too socialist to understand properly.
The median income of a French household puts it in Alabama (Alabama is wealthier). If you truly believe that the US is a capitalist hellscape where only the fittest survive, Americans are more than fit enough. It's not even like rent is affordable in Europe; young people feel the same squeeze but with far less opportunity.
Europe regulates itself out of the competition. If you're OK with living in a stagnating economy while youth unemployment stays above 15%, sure - but let's be clear that you've still got billionaires and unlike in the US they actually succeed in using the government to protect their monopolies.
Europe is great to live in if you have a home and a job. It's much, much worse if you're an ambitious young person looking to make a mark on the world, and reducing that to "salary is everything" is imo very sad.
