Colleges in the US are surperior to those in France (and Europe),
I think this pretty much sums it up.
although secondary school might be an adantage for Europe. A lot of Europeans study abroad in the US all 4 years. In less wealthy European countires (Spain, Italy, etc) a degree over there doesn't even matter because there aren't any jobs outside of the major cities.
Wow. Where to begin? First of all, Spain and Italy aren't "less wealthy" EU countries. Out of the 27 EU members, Italy and Spain rank 12th and 13th, respectively, in gross national income. The per capita income is 2-3x that of poorer countries like Latvia and Lithuania. You seem to have Spain in 2009 confused with Mexico in 1809. Also, EU members can travel freely and seek employment within the member countries. Sort of like leaving a podunk town in the US for opportunities in a bigger city.
France's higher education system, particularly the Grandes écoles, is on par with American Ivy Leagues and Cambridge/Oxford in the UK. While American "higher education" factories pump out thousands of Art History, Religion, and Communications majors, European schools emphasize applied sciences, engineering, and mathematics. It is true that US Universities still attract the best and brightest post-grads to their science and engineering programs, which is why these classes are full of foreign students.
This might help explain why 1 in 5 Americans believe the sun revolves around the earth.
