It's why so few companies want to invest in France and things like Activision Blizzard closing all their French offices. And of course, the radically lower salaries there.
This has absolutely nothing to do with companies wanting to invest in France - or not. Blizzard closing its Versailles HQ is also a very bad example, one, because they are in a middle of a massive crisis, and two, because the move was motivated by unnecessary greed and it will most likely cost them an arm and a leg in severance packages.
