It's almost as comparing apples to oranges. Taxation differences between US states is incomparable to that of semi-socialist European countries.
From the link above:
The general conclusion is that moderate tax increases on the rich, even if no neighboring jurisdictions follow suit, is unlikely to lead to much in the way of emigration.
Squirming again? Or should I say twisting facts?

Nope, sorry. Your argument is that higher taxes drive the rich away, see...
Economically active people and businesses leave the country for jurisdictions with lower taxation (UK for example)
That's simply not true, mostly because wealthy people aren't stupid and they understand that you have to pay to play. You want to live in a nice society? You're going to pay higher taxes for it. You want people to actually be health and alive enough (not to mention have enough disposable income) to buy your products? You're going to have to subsidize them. One hand washes the other. The rich understand why they pay more in taxes. It's the igornant poor (like yourself) that are the ones crying for lower taxes on the rich.
If the rich want to be taxed higher, then why don't they donate rather than get "taxed"? Can't they do so on their own without dragging others in with them?
