This is not entirely true, as in France your payroll and sosec taxes are much higher than in U.S , you're only accounting for income taxing in your equation, you talk about people making 5000EUR but you leave out the part is that the 5000EUR that the person is making was already heavily taxed before he got it, then taxed again once it reached his pocket, between all Social Security taxes, unemployment, welfare, health, etc. if you got paid 5000EUR per month, your employer actually paid WAYYY over 7000EUR for you, is just that the other +++2000EUR you never saw because it went straight to the government, only 5000 made it to your bank account, which will later on...be once again taxed, and at the very end of the day when all the money was taxed, you'll be probably left with your employer having paid around 8000EUR for your labour, and you actually recieving a net of 4000EUR for yourself to go spend or save in whatever you want.
Not to mention you're terribly wrong about healthcare in U.S , first off...U.S has the best QUALITY of health insurance and medical treatment in the entire planet, with Singapore, China, South Korea and Japan following up but not very close, Europe would come after them and that's only Scandinavian countries, where Europe leads is in avialability...and that still doesn't apply to every single country in the Union, but also...what 9000$ are you talking about??? an individual plan for an average young worker will cost around 3 to 5K per year depending on the state, and no matter the price, it will be of much greater quality than the statized solution you've got in Europe.
While your comment sounds great for leftist statist colectivist Europeans (as 90% of European citizens are) it's filled with half-truths and straight up lies, doesn't resist the minimum research nor actual half-ass analysis.
"France aren't that high when compared to US"
