This is the sort of thing China (used to) like. Ask them how the "1 kid" policy worked.
As others have said, we really want the government engaged in population control? Is overpopulation even a problem in this country?
One thing is correct, as wealth continues to concentrate at the top something will have to give. I guess this would be one way that the ultra-rich could keep the hordes away from their gates (for a while). Gee, sounds like a great country to live in. More like the world of Elysium or any number of other future dystopias from stories.
