That's unlikely due to extremely high taxes in the EU for individuals. People who know their stuff tend to migrate where they get more in return for their talents.
When I moved to the US my nominal salary tripled but my quality of life dropped noticeably. The first part I knew going in, the 2nd part came as a total surprise.
Taxes actually come out about the same when you add the multitude of separate tax systems in the US (federal income, social security/medicare, state, local), and then in the US additionally have to pay extra for things that are paid by taxes in Europe, health care being the biggest such expense.
And then there is the expectation of working 24/7, nobody has much vacation and nobody takes what they get, etc etc etc. Yeah, quality of life for Americans is nowhere comparable to Europeans, unless you're in the "I no longer work for money, my money works for money" set.
I migrated from the EU to the US, but then realised that once everything was factored in (medical, car, housing, cost of living) the taxes were actually worth it, so I moved back to the EU.
Hmm. Admittedly it was a long time ago buy I moved from a (then) EU country to the US and from my perspective taxes are about the same. And in the US we have to pay for a bunch of stuff that is government funded in EU.
What I pay for in medical insurance and routine medical expenses pushes me is just about equal to the difference between my current US taxes and European tax rates - and I'm a fairly healthy person with no chronic conditions.
Frankly, I don't see the point of celebrating the fact that my money is going to private companies as premiums/co-payments rather than to the central government as taxes, while getting worse medical outcomes for it (with a risk of medical bankruptcy).
When you have more complex health problems, you'll notice though that you still have to use private healthcare, because state provided is next to useless.
Taking what you said at face value - this doesn't give an advantage to either system when it comes to the minority of people who have complex health problems. In practice, European private healthcare is likely to have more price transparency and cheaper costs due to the pricing of procedures and medical consumables having been negotiated/capped by a government agency or an independent body.
