CAs tax rate when you factor in federal tax is comparable to the EU and we get none of the benefits.
Nominal rates might be, but tax burden is not. California tax burden is well under 15% GDP, and federal collections in the state are a tiny bit higher than state tax revenues, together still under 30% tax burden. EU overall tax burden is over 40% of GDP.
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.
Perhaps the european model is better overall, or perhaps there are other complications. Regardless, the debate is not "free" vs "pay private companies". Both models have costs and benefits.
