Recommend reading the book Camp of the Saints by Jean Raspail, about a flood of third world refugees overrunning Europe. Several Freepers have mentioned it in this forum already, as has Steve Bannon recently. Oddly enough the price on Amazon is now $2,500 for a hardcover copy, and $135 for a paperback. It won't download to Kindle, but I did find a copy of it online, which I downloaded. It's prescient and enlightening.
Maybe one can get a copy of “Camp of the Saints” through interlibrary loan? I have gotten some hard to get books through it.
