Quote from DataExec:
Bashing the addition of 550,000 legal, immigrant workers is an overly simplistic approach to a complex problem in America.
True, we are facing rising unemployment (6.1% and growing) due to a recession, a slowdown in construction and a meltdown in the financial industries. This will cascade into more unemployment as credit tightens causing an increase in business failures.
Neither the recession nor the subsequent rise in unemployment is caused by immigrant workers.
On the contrary, there is a shortage of skilled workers, especially engineers, in certain industries (oil exploration, biotech, software development, aerospace, etc.).
The chronic problem of getting visas for skilled workers is causing many companies to "go global" to solve the problem. An example is Microsoft opening a new research and development center this past year in Vancouver, Canada. A quote from Microsoft --
"...allows the company to recruit and retain highly skilled people affected by immigration issues in the U.S."
They also have an R&D center with 350+ in Hong Kong, a facility in Toronto and others planned around the world.
Shut down the entry of skilled workers and the companies will move operations overseas.
