The elites want as much skilled immigration as they can get, yet even the Washington Post admits there aren't enough jobs for all the laboratory scientists who are here now.

From "U.S. pushes for more scientists, but the jobs aren’t there" (link) by Brian Vastag:

...There are too many laboratory scientists for too few jobs.

That reality runs counter to messages sent by President Obama and the National Science Foundation and other influential groups, who in recent years have called for U.S. universities to churn out more scientists.

Obama has made science education a priority, launching a White House science fair to get young people interested in the field.

But it’s questionable whether those youths will be able to find work when they get a PhD. Although jobs in some high-tech areas, especially computer and petroleum engineering, seem to be booming, the market is much tighter for lab-bound scientists — those seeking new discoveries in biology, chemistry and medicine...

...a decade of slash-and-burn mergers; stagnating profit; exporting of jobs to India, China and Europe; and declining investment in research and development have dramatically shrunk the U.S. drug industry, with research positions taking heavy hits.

Since 2000, U.S. drug firms have slashed 300,000 jobs, according to an analysis by consulting firm Challenger, Gray & Christmas...

...Largely because of drug industry cuts, the unemployment rate among chemists now stands at its highest mark in 40 years, at 4.6 percent, according to the American Chemical Society, which has 164,000 members. For young chemists, the picture is much worse. Just 38 percent of new PhD chemists were employed in 2011, according to a recent ACS survey...

The article doesn't mention skilled immigration for one reason or another. However, the high skilled immigration that the elites want would only make the situation worse. Yes, some number of those immigrants would start companies employing others, but most would become competition in an already weak job market.

Those who want more skilled immigration include Obama (see Obama immigration), Mitt Romney, the establishment media, the two major parties and more. For instance, Romney, Obama, and several others have said that they'd "staple a Green Card" to the diplomas of foreign citizens graduating with advanced degrees from U.S. universities.

That doesn't mean that we should disincentivize science careers, just that we should cut back on the immigration of those who'd just be yet more competition in a weak market.
