I am not saying whether the European system is better or far worse, just explaining why our systems permit free studies easily.
France is clearly lacking of interesting jobs (SII) in IT, expect research maybe. Europe is also far from having a perfect society, but nothing is black or white, just gray.
I was working only few weeks ago in Hong-Kong for the biggest French bank in HFT and had a decent salary as a graduated. Hong-Kong follows the US style. I was asked to move to NY for 1XXk but finally opted for a life in Sweden for many other reasons. Anyway, I did my research about NY.
With the 1XXk in NY, you must pay a 3000$ * 12 rent (36k) for a 40m², put 1/3 for a future retirement and in case of a terrible health problem (30k$). When you get children, you must pay everything by your own, like fees for 2 children = 15000$ * 2 (30k$). Plus you work 30% hours more, hence make 30% more per hour. Statistically, Americans are richer, so it must be interesting to move there especially when single. It highly depends on your life style and your expected work-life balance.
