Immigration Lifts Wages, Report Says (Lori Montgomery, Washington Post, 21 June 2007):
More than 90 percent of native workers benefit from the influx of low-wage labor because immigrants take jobs that complement higher-paid native workers rather than competing with them, according to the report. For example… immigrant roofers lower costs for contractors and home-builders, creating jobs for plumbers and electricians and lowering the price of houses for consumers.
The losers are native workers who compete directly with immigrants in certain job categories, though the impact on their earnings is small compared with other factors, such as technological advances, globalization and minimum wage levels, said Giovanni Peri, an economics professor at the University of California at Davis.
“There’s this aversion to immigration, but people should be much more averse to computers,” Peri said. “They are much more responsible for the bad effects” on U.S. workers.
But, but… I use an AMERICAN computer.

I doubt my friends that are still trying to make a living doing: drywall, painting, carpet installation, or carpentry would agree. As the number of “new” Latin American construction workers burgeoned in Colorado, (anecdotally they appear to speak only Spanish), framing prices have dropped from $5.00-$6.00 per square ft. to rougly $3.20 per sq. ft. Yep, that sure benefits lots of US tradesmen.
They have to hire professional services, like Katy Electrician and instituted strong security measures to protect their business.
