But there's also a modern test case which is often overlooked: Puerto Rico. The island is a US territory and has most of the benefits that come with being part of the US, but it's entirely exempt from federal income taxes. If taxes are really such a problem, Puerto Rico should be an economic boom zone, and rich Americans should be flocking to reside there to escape federal income taxes.
Is that the case? Well, no. Almost half the population lives below the US poverty line. And there seems to be no flow of wealthy people leaving the mainland US to take up residence there.
Right-wing claims about the disastrous results of restoring normal tax levels are just another case of a hypothesis that sounds superficially logical but isn't supported by what happens in the real world.
