'clear net benefit'

Diversity is nice if immigrants are willing to assimilate, learn the native language and they are well vetted, and you have the capacity from a practical perspective that they bring a clear net benefit to the country.

Perhaps the same should apply to the indigenous population too. It could be heaven with all the problems "cannonballed" to North Korea.
