Does it cover stuff like cosmetic dermatology, full dental plan (implants) ? I don't live in France, I lived in different EU countries and every time I needed something the "free health care" meant I had to pay participation fee and wait 6 months walking around appointments and ended up going private clinic. I basically got 0 value out it, considering I'm young and healthy I would not have to pay much for insurance, you're mostly footing the bill for the pensioners.
>free university
Which again means nothing to anyone immigrating as a skilled worker
>pension contributions,
I sincerely doubt that by the time I hit retirement age the pension system will look anything like it does now because of multiple factors (current pension funds being structured around social transfers and constant employment growth, meanwhile automation replacing a large % of workforce permanently). Again just transfer payments to old people.
>5-7 weeks paid leave and generous unemployment insurance amongst other things
So you're going to emigrate as an expert in a sector earning top ~10-1% income for unemployment benefits ?
If you're a young professional either none of the things you listed matter to you or there are better countries than in Europe by those criteria (Nordics/Switzerland).
