What's needed to discourage illegal immigration into the United States has been known for years: Enforce existing law.
Amazingly, that is happening now — to some degree… Immigration prosecutions reached an all-time high in March, reports the Transactional Records Access Clearinghouse (TRAC), a data research and distribution group at Syracuse University in New York. Using data from the Justice Department, it calculates that prosecutions were up 49 percent from February and 72.7 percent from March of last year…
If current moves to restrain illegal immigration trim that growth by 100,000 to 200,000 immigrants, it should have some effect on the nation's labor supply, notes University of Chicago economist Jeffrey Grogger. He's coauthor of a paper calculating that a 10 percent increase in the supply of a particular skill group caused by higher immigration prompted a reduction in the wages of similarly low-skilled black men by 4 percent between 1960 and 2000, lowered their employment rate by a huge 3.5 percentage points, and increased their incarceration rate by almost a full percentage point.

Apparently the logic of this has even occurred to the Socialist Government of Spain, which when it came to power in 2004 irritated other EU partners by legalizing huge amounts of illegal immigrants (which meant they could go anywhere in the European Community).
Now, the Spanish, faced with a huge property market slump and soaring unemployment, have proposed paying immigrants to go home! Spain will pay unemployed migrant workers to leave By Lisa Abend and Geoff Pingree Christian Science Monitor June 20 2008
The incentive program signals a shift in Spain's famously lenient immigration policy. In 2005, Jos?© Luis Rodr?guez Zapatero's Socialist government sparked the ire of other European countries when it gave work and residence visas to 800,000 immigrants. Now the government has not only supported the European Union's Return Directive for undocumented workers but has taken a more skeptical approach to legal migrants who fill construction and domestic jobs. The Labor Ministry is studying a plan to restrict family immigration to parents and their children under 18. Currently the law allows grandparents and in-laws to join their families.
This idea has received very little attention in the orthodox US MSM, with the honorable exception (for once) of The Wall Street Journal
Spain Proposes Paying Jobless Immigrants to Return Home By JONATHAN HOUSE June 20, 2008; Page A8
In a year when Presidential candidates are proposing huge bounties for scientific invention, which will be the first to propose relieving working class Americans with this idea?
