Switzerland is doing pretty good. It is the only country where I know the citizens say we have decided instead of the government has decided. Oh, and they do pay taxes.
I never understand how people point to existing systems that are working for a country, and then make the (valid) point that the success of those policies can't necessarily be extrapolated to another country, but then (invalidly) believe that is a suficient statement to end the conversation.
Especially because those people often are talking about countries with some form of democratic socialism (where there are a number of strong success cases), and instead frequently put forward libertarianism - which is a completely untested government form in any country.
Switzerland sustains itself with a huge influx of foreign money by adopting policies attractive to the wealthy. That strategy can't be pursued by every nation on the planet.
