Though given our reaction to the current wave of refugees, we will blame the refugees for their own predicament and probably George Soros, as is tradition, long before we accept any blame ourselves.

I suspect you may be right that the popular option will be to close the border. I do not agree however, that it is the better option.

Main point is, if you’re seeking refuge, try to put a clear-cut reason down rather than something debatable, but sensible, like absolute poverty.
This will certainly happen in a scenario where there are massive refugee populations elsewhere in the world.
Nothing “simply” about it.
One million people is a single city. You do have a problem if one million people are suddenly relocating. It has happened before for war, natural disasters or other reasons.
Migrating a billion people is not a thing, for the simple fact that there isn't any human settlement any close to approaching a billion people. If you're talking about the scale of a whole continent, migratory flux span over a lifetime and are not homogeneous.
