> Has Europe’s pro-union climate led to more competitive software companies, or better pay and benefits for its software engineers?

E.g. we get health insurance even if we quit or switch jobs.

The thing about European software companies tho is that they are hardly unionized at all.

>Every European engineer I talk to seems either amazed or resentful about American software engineers’ salaries and benefits.

I am not, to be honest. Sure, at a first glance it might seem the US devs make tons of money. But once you account for cost of living (like the astronomical rents in every major tech hub city) things do not look that rosy anymore. I know US people who make twice or trice what I make, and yet they live in dumps that you can hardly call apartment and they say they cannot afford any better. That, combined with the at-will nature of US employment, really doesn't strike me as desirable.

I like living in a country where I have a pretty awesome standard of living, a nice apartment that I don't have to share (unless I want to) and a safety net that is (at least for now) able to catch me should I ever struggle or become sick, so I won't go homeless.

Those things are largely thanks to work the unions did in the past and keep doing.

Certainly, the salaries are a bit of an illusion when you take the insane housing costs of the Bay Area into account.

If breaking up the American tech companies helped disperse jobs outside of Silicon Valley, that would be a good thing.

Europe is really diverse in wealth and business climate. The wealth gap between different European nations is so large that the US probably seems like the pinnacle of equality. It's hard to talk about Europe in general in this sense. I've worked as a developer, where I made less than $600-800 a month. Although I was underpaid, but it probably wouldn't have been possible to make double that in my country. I think you might want to dial your question in slightly more than "Europe", perhaps "Western Europe".
