The Camp of the Saints has become a classic because of its provocative plot—migrants essentially take over the country to which they migrate. Judging by the excerpts in this article, it is also well written. From Beau Albrech at unz.com:

Jean Raspail
Le Camp des Saints
Editions Robert Laffont, 1973
What if in some surreally bizarre future, an invasion took place not by hordes armed with rifles and artillery, but by hordes armed with pity and guilt? Today, it’s quite obvious to all who can see that the future is now. This outcome, and the Endless Night that followed, was predicted by Jean Raspail in his best known work, The Camp of the Saints.
This was first published in 1973, and has been much discussed since then. I recall that it made a bit of a splash during the 1990s immigration debate. For example, I noted a newspaper column in which some Latina talking head, a figure in an immigration advocacy outfit or such-like, hotly dismissed The Coup [sic.] Of the Saints as a “racist fantasy.” Well, gosh, I guess that’s all we need to know about it, right? The book did get better acclaim than that elsewhere.
Jean Raspail himself distributed autographed copies to French notables all over the political map. Surprisingly, several leftists – even the big banana François Mitterrand – wrote back with kind regards for the author in private, even the ones who didn’t agree with the message. Oddly enough, some did agree, such as the Socialist writer Max Gallo. Such courtesy and divergence from the globalist hymnal hardly seems possible!
On this side of the pond, President Reagan found the book quite impressive. This is the great conservative hero who unfortunately legalized a few million illegal aliens back in 1986. (The deal was that after this, then the Republicans would fix the immigration problem, boy howdy!) In so doing, Reagan turned his beloved California into a permanent blue state which now has 54 Electoral College votes. William F. Buckley also had kind regards for The Camp Of the Saints. He was undeniably quite talented, though the sneaky snake of Con Inc. oversaw decades of salami-slicing purges from his flagship magazine. This was to the detriment of paleocons who wanted to fix the immigration problem for real. Both Reagan and Buckley were highly influential, and apparently they knew the score at least to some degree, yet they failed to make the right decisions.
There is the Magic Soil (s/) and they are teaching their children that it is all about race/tribe while whites are on some faculty lounge John Lenin Imagine horseshit.
Dumbed down to stupid level isn’t going to work out.
Stock up on sunglasses for the bright future that awaits.
