Has Europe solved these things? I lived in France for a number of years and unemployment, especially outside of Paris is very high, the economy is in the doldrums (especially in smaller cities like Avignon,) the Maghreb continue to be treated like second class citizens, and terrorism is a very real and continual threat. Health insurance is good, but the system is running huge deficits. And gun violence? Spend a few minutes with the Marseille police and you’ll see the gangland violence is dramatic. As far as income inequality— that’s debatable. The upper classes are kept from getting too “upper,” but the lower classes still live in decaying concrete block housing. Americans also have about $14,000 more per year in disposable income compared to the French — that’s after accounting for insurance, education, etc. The very poor do better in France, but should we be optimizing society around the ultra-poor? Doing that means that everyone else is worse off and the ultra poor are still pretty poor. As far as transportation, spend some time in smaller French towns. You better hope you have a car or you aren’t going anywhere. There is also the high cost and oppressive regulation around starting a business. Entrepreneurship in France is very difficult despite the word itself being invented there. France rewards mediocrity.
