Have you ever spent any time in France? As an American who lived in France for four years, I beg to differ. It is a wonderful place to live: beautiful scenery, good food, friendly people, plenty of leisure time, etc. On your train comment, I was impacted by a rail strike once in the 4 years I lived there. The French TGV (high-speed train) goes three times as fast as our trains in the US, so you waste a lot less time when you are on the train compared to the US. Which is better, wasting a couple of hours every time you take the train, or being impacted by a strike every few years?
If you think there is no individualism in France, all I can say is you must not have spent any time there. I met some of the most unique people I have ever seen.
As far as the tax situation, I was good friends with a number of engineers in France who were basically in the same socio-economic situation I was in, and it seems to come out about the same as in the US. Yes, they pay higher taxes, but in exchange, health care and education are nearly free, and retirement is taken care of. Have you tried putting anyone through college in the US lately? - count on 250K$ when all is said and done. What I saw was that the US engineers have more take-home pay, but they end up saving it all to pay for retirement, college, and health care.
