> How do these numbers look when you count health care/insurance cost for CA instead of only for EU?

Then you are counting the cost of the thing you are complaining about not getting for your supposedly-equivalent taxes in order to try to justify the claim that the taxes are equal.

Count school fees and student debt too - public schools in most of the EU are good enough that you don’t have to go private the way the US does.

You don't need to go private in the US, either, that's largely a status display and a mechanism for non-educational social benefits more than an actual educational benefit; like the difference between outcomes in different public schools outcomes, the vast majority of difference between education outcomes in private and public schools is explained by factors outside of the school attended that determine educational outcomes (socioeconomic status, parental educational attainment, engaged parenting, etc.)
