I don't believe there is much hope of that happening.
Despite the way the book is being presented by some, the focus of the book is on the taking over of the culture-forming institutions in the West by quasi-Marxists, who have used their position of influence to preach hatred of Christianity of the West. The end result is the triumph of political correctness we see today. Buchanan treats the declining birth rates throughout the West primarily as a symptom of this broader Marxist-inspired malaise.
Since people seem focused on the immigration debate, though, Buchanan has the facts on his side there as well. As Harvard economist (and Cuban immigrant) George Borjas has shown, current immigrants are MORE likely than native-born Americans to get government handouts. As the National Reserach Center's study showed, mass immigration is NOT necessary to the American economy: that study found the net contribution to the economy from immigration was on the order of ten billion, a paltry sum in an eight trillion dollar economy. And economists have also found that this benefit has come at a cost, the declining wages of working-class Americans. Finally, as the 2000 election returns showed, immigrants are MORE likely than native-born Americans to vote for liberals.
As usual, Buchanan has facts and logic on his side, and all the politically correct can do is whine and call him names.
Well, those are two things you are obviously lacking.
