Supporters of the proposed law say that something is needed since Americans simply refuse certain backbreaking jobs in construction, agriculture, hotels and restaurants. But such understandable pessimism rests on many questionable suppositions.

It assumes, for instance, that the traditional remedies of the free market for scarce workers--mechanization and increased wages--ceased to work around 1980; that it is hard to sleep or dine out or find a cut lawn in an Iowa or Maine where there are not tens of thousands of illegal workers; that the experience of guest-workers in Germany and France provides encouraging analogies for importing cheap labor, that Californians or Texans once did not do most of their own work before the influx of industrious aliens; and that it is economically beneficial and morally sound to use foreign workers when millions of Americans remain unemployed.
