I’m in France and my cousin married an American.
Cost of living is high and the language is bullshit, but the standards of living are some of the best in the world. Very old established democracy and rule of law, workers rights, social security, and whatever the complete opposite of political apathy is. Culture is rich with a disproportionate level of global relevance for the country’s size. The location is ideal in the middle of europe, with a good variety of landscapes and climate.
Internet is cheap and fast, but i don’t know anything about the state of tech jobs.
I don’t know much about the tax system either but my assumption is you might save money just on the healthcare alone.
Overall i wouldn’t recommend, you’d be better off in a country with a language closer to english, such as most countries north of France. They’ll have better english proficiency and you’ll learn the language easier.
Yeah i don’t think it’s worth learning french for almost any reason, lots more people speak spanish
