I wont argue that those two things don't exist, but can you show some proof that GDP is measuring nothing else than ("just") those two things, and that there are meaningful differences between the EU and the US with regard to these two things? Is there no unreported inflation and no money printing in the EU? If that were true, we'd see massive devaluation of USD vs. EUR.

Also, if you don't like GDP, you can just look at real wages – same picture.
