Let's assume that the US did have "better business results" and let's also assume that that is the result of worse working conditions. Why then are the workers, working in worse conditions, not benefiting from it directly?
Seems like, if that were true, the US is working average workers harder so that the ultra-wealthy can get even wealthier. Does that benefit society at large?
PS - I'd like to link this, called "The Nordic Model"[1] discusses a lot of good (and bad) about that part of the world.
