Yes, and this does not apply to people that cannot and will not move. They can tax them quite a lot before they leave their mother and god alone. And they are doing it. See my post here:
Hahaha! The world is simple. The more you travel and the less local you are, the less you pay and the more you get. Always been like that, always be like that. The reason why foreigners pay less is not discrmination, it is just a result of them being able and willing to move. it is a free market.However, I feel bad for the locals because they pay more taxes than foreigners.
