This is how much US owns currently to the whole world
:U.S. NATIONAL DEBT CLOCK
Is is so much money that we doubt you yeahso
even know how this number is properly called.
EU has been created exactly to give US the opposite monetary structure. As the results dollar now is not the strongest currency in the world anymore.
Regarding the EU - Germans work because they can't live just because of tourism and travelers, on the other hand countries you mentioned work and live for thousands years already exactly because of that (mostly).
Here you compare to the countries with strong economics, but don't forget EU has been joined recently by 3rd world countries with the post-socialism structure, incl. Latvia. I think that was their primary mistake... because Germans, Spaniards, Greeks really work, Latvia just washes the money
