Re: Quality over quantity
Most unselective migration is the result of desperation. Take a look at what's happening not just in the US but in Australia and throughout Europe. Millions of people are basically fleeing a death sentence for just a chance elsewhere. With the Grim Reaper at their heels, they have the most powerful motivations to persevere. Put a wall up and they'll just find a way to get past it. In the US, they use tunnels or hit the boonies. In Europe, they cut fences. In Australia, they make mad dashes in overloaded boats. AND the UN's getting on everyone's cases to stop being so cruel to the disadvantaged.
