I live in New York City. My taxes (as a percentage of my income) are substantially lower than they would be if I worked the same job in London, Berlin, Paris, Stockholm, Amsterdam, or any of the European cities that are considered to be "tech hubs".

...so? That's the case in most of Europe too, with the UK being the main exception. Most European companies use some form of private insurance or have out-of-pocket expenditures.
As far as I'm concerned, none of those "problems" exist. I have no monthly premiums to pay, most copays are $0 or close to it, and I don't think twice about finding in-network providers. It's much easier for me to book a specialist if I need to than it would be in any of those other cities.
