This is the kind of thing that can break entire economies: forcing you to hire people you don't want to hire, people who may be entirely unoptimal but you have to hire them anyway due to a quota. Of course the consequences will be too gradual to see at first. People will only implement this stuff slowly, fines will probably not appear for a decade and by the time these changes are actually in effect nobody will know why the economy runs X% worse than before. It will be as if it has always been slightly bad and economists will ponder for years and years how to improve the ailing continent.
