alt Hacker NewsUS software companies (Google, Meta, MS, etc) have offices in Paris and they pay way more than that. Especially if you take into account total comp (Mistral is private so any stocks you get are "locked" until IPO or sell out)
Yes 90k is more than most French software companies pay, but the salary needs to be competitive with those US companies.
When I was in Germany a few years ago, I was browsing jobs available in France and most software development jobs were under $55K USD. I don't know how you're supposed to survive on that. You can probably make more money as a waiter.
Germany is not so great either in that sense though at least in crypto sector, the pay was reasonable... Though as a job it was total BS.
UK was pretty good at some point (though all the really good jobs were gate-kept by IR35 regulations), The Netherlands was pretty good (especially contract roles thanks to big tax discounts for foreigners). But IMO, one of the best countries outside of the US for software work has been Australia. I actually came back to Australia because of it. Though it's not quite as lucrative today but it's certainly still much better paid than France and has potential.
That said, if you want to do your own startup and you do not have special business connections or pedigree, then the US is the only real option IMO.
I think it comes down to easy money. Easy come, easy go. To be rich enough to invest in startups in France, you need to be born into old money or be a complete freak of nature. These kinds of people don't part with their money easily. They need a guaranteed return and they can't rely on any media channel to bring traffic. If you live outside of the US, all media channels are essentially working against you; you can literally feel that and so everything is riskier. It's like playing the same game with a massive handicap.
