Yes we can. All "we" need is the political will, which has been sorely lacking.

True, though with how things have gone the past 20+ years, you'd have to ban immigrants from most of Europe, and I doubt any President (Trump or anyone else) would be willing to do that.

Perhaps the best solution would be what some in this thread have suggested - just institute a moratorium on immigration, period.
