The West is too cowed by guilt to look honestly at immigration.
Is immigrating from less-developed countries to the West a good or a bad thing, for host and guest? Is the immigrant angry at, or nostalgic for, the country he left? Is he thankful to or resentful of the country he has come to? Does the Westerner know why the other seeks him out or why he himself chooses not to emigrate to the non-West? These questions and dozens like them are not so much never answered as never even asked.
