I agree it is a big decision to relocate to a country based upon the premise of reducing or eliminating your exposure to tax. In some cases as I have already said it may be justified. There is a point where government incompetence and corruption will seem beyond repair and flight is justified. In many others though I suspect the major motives are selfish. If you remove yourself from the economy and society which raised and enriched you to escape contributing some of your gains via taxation, you are abandoning that society to some degree for selfish motives...and your incentive to be involved in the politics of that original nation will be inherently much reduced. I am son of an immigrant who sought a better life- away from the crippling class structure and post war decline of Britain. Here in New Zealand he had opportunities that would have been very unlikely if not impossible to realise back in the UK. But here in NZ we still tax progressively recognising that those who enjoy the most success from our economy are best positioned to contribute to the cost of government- there are often and increasingly loud cries from the most wealthy and their lobbyists that if we raise taxes too high they will flee somewhere else - I say good riddance to them - we do not need the selfish greedy rich pricks who refuse to acknowledge the origin of their wealth is largely in the economy and governance that enabled it. Yes they often worked hard but it was in the context of a democratic and lawful environment enjoying significant economic and cultural privilege relative to most nations of the world. In most cases these threats are anyway hollow bluster as these peoples wealth is mostly vested in assets and property located here and not easily relocated. But if they do choose to leave their arrogance and greed is imo, best relocated elsewhere to fester and spoil whatever locale is unfortunate enough to receive them and their kind.
