The basic problem is that the nation's economy is ravenous for more immigrant labor than the system of legal immigration can currently provide. Furthermore, about 11 million illegal immigrants are in America. It would take a lot of buses -- 200,000 of them, bumper-to-bumper in a convoy 1,700 miles long -- to carry them back to America's border. America will not do that -- will not round up and deport the equivalent of the population of Ohio.
No, part of the problem is that Americans are consumers first and citizens second. Our bacon, lettuce and tomatoes must be cheap, no matter what the cost. Our political culture is also decayed and corrupt. As far as I could tell, no attention was paid to this critically important issue in the 2004 presidential campaign.
Note also, the patently phony choice Will presents to the reader. Apparently, we can either round up 11 million illegals in a mass deportation, or capitulate.
