TEXTO:
Immigration in the United States
Immigrants are good for our economy. The most
skilled create jobs in technology and engineering, says
Duke professor Vivek Wadhwa, who estimates that in
2005 immigrant-founded engineering and tech companies
[5] employed 450,000 people and generated $52 billion in
sales. But even the least skilled more than repay their
costs in school and health care. Two highly respected
Australian economists, Maureen Rimmer and Peter
Dixon, studied the issue for the libertarian Cato Institute.
[10] “The net impact on U.S. households from tighter border
enforcement is unambiguously negative,” they found,
because even low-skilled immigrants expand the
economic pie and create jobs farther up the ladder. Cato’s
dan Griswold says the study shows a $250 billion
[15] difference between the most and least restrictive
immigration policies.
