Except that most people in developed countries see America as all nice and fuzzy until they get down to the gory details.
People outside the US *like* their month of time off every year. They *like* having their working hours be limited to a sane amount. The US is nice for them to visit. Few want to stay once the details become known.
BTW – in the 20th century, working hours were historically longer abroad than in the US. It’s only recently (past 2-3 decades) that the situation flipped. This didn’t actually make the US any less competitive.
