If somebody is willing to move for lowering the taxburden, here is a novel idea: Why not pay the same tax, but move where the cost of living is much lower? Then everything stays legal, but the income's purchasing power is going to increase, and probably happiness will be achieved. So if you live in NYC, you could move to the Kentucky countryside, or if you already live in the country, you can move to India or a Mexican gated community. The possibilities are limitless....
Why not do both? Your argument makes no sense. Yeah I get it, we can all move to India to increase our purchasing power. Here is a better idea, let's just end the welfare state in this country. Problem solved.
