I think when you factor in purchasing power parity it goes the other way. Food and non-coastal housing in the US is pretty cheap.
Also, it's much cheaper to live well in a certain style in the US away from the coasts than in Europe. Bubba has a large house, two trucks, a few acres of land, ATVs, a hunting cabin, and hunting licenses. Francois has a small house, pretty much no land, and a single small sedan. Francois might make more money in absolute terms but Bubba would never agree to swap.
