That's a great bunch of cherries you picked there. If you are comparing Europe to the US, comparing France and Mississippi is disingenuous. Compare best-to-best or worst-to-worst [1][2]. The worst European countries are Azerbaijan (66.9), Moldova (70.2), Ukraine (71.2). The worst US states are W Virginia (74.8), Mississippi (74.9), Alabama (75.5). The best EU countries are Norway (83.2), Switzerland (83.1), Iceland (83.1). In the US, it's Hawaii (82.3), California (81.7), New York (81.4).
In short, the best of US is somewhat worse than the best of EU. The worst of US is fares much better than the worst of EU.
