According to
this report, in the US, people are migrating from high-tax states (such as New York, Ohio, and Massachusetts) to lower-tax states (such as Florida and Texas). So much so that, after the next census report is released, there's expected to be a net shift in congressional seats.
So, let me get this straight - you raise taxes too much, and people will move someplace where their taxes are lower? Hmm - is anyone in any level of government up here paying attention to this?
