Isn't It a Problem of Emigration?

What may be right for one stage in the development of an economy may not be right for another. As hong kong is a marvellous example, just because its circumstances are so terrible and people would love to get elsewhere if other people would let them in. This is a problem of emigration, which is a very important restriction on human freedom. In the period before 19 13, we had complete, a hundred % freedom of emigrate into the united states. We don't know how long it will take until that happens again.
