At that level you will pay 800€ per month for public health insurance (it's a percentage up to about 65K income, then capped). Public health insurance allows you to cover children and non-working spouses for free.
If you are curious about US insurance plans, here is California website for estimating insurance costs. Basically the costs scale with income, number of individuals and their age and their desired level of coverage.
For comparison, Germany is at 51%, UK at 50%, Netherlands at 47%.
Belgium is close to France at about 61%...
The US (not in Europe, obviously) is at 46%.
And Switzerland at 36%; this is the European outlier in the opposite direction from France.
But a priori, just from this data I would expect French taxes to be about 1.4x US taxes and Dutch taxes to be similar to US ones...
For example, I used someone in New Jersey (a US state known to be high-tax) vs France at a salary of 100K (which is the same in Euros now!): In NJ, including Federal, state and sales taxes, total tax is $27K. That seems to be a far cry from the $41K (sorry, Euro) I get in France from a very basic calculator that only includes country-level taxes AFAICT.
