Sure, but it's not just that. The quality of life could be argued to be significantly higher than in other places.
The job security once you land a decent gig is not something to be discarded. This being said, Macron does plan on making it easier for people to be fired, in order to make it easier for companies to hire. This is a big topic that I could rant for hours about.
You do get all-inclusive health care. In addition to what the government provides, most 40k€ jobs will come with an extra private insurance ("mutuelle"), which will effectively reduce health costs for you and your family to 0. Depending on how nice your company is, you might be _taxed_ on an extra 20-40€ of monthly income, which gives mutuelle rights to you and your family. If you're unlucky, 20-40€ will be deducted from your pay for every family member on the mutuelle. This is usually not negotiable as it is managed/negotiated by the employee representatives/unions.
You also get fairly decent rents. 600€/month will get you a flat in any city, except Paris/Lyon. 1000-1400€ will get you a nice place in most cities.
You also get access to a decent transportation network to most Europe, and a very good internet connectivity, at the consumer level.
I moved from France to Denmark. I would say my wealth has increased (2-3x salary increase), but my overall stress has massively increased. France has a lot of good things going for it.
