Writing in the Wall Street Journal, a professor from the University of California, San Diego, argues that an expanded guest worker program might be less desirable than the status quo. Given the likelihood that politicians and bureaucrats will sabotage even a good idea with needless regulation and red tape, this is a compelling argument:
...from a purely economic perspective, illegal immigration is arguably preferable to legal immigration. ...the illegal route is for the moment vastly more efficient than the cumbersome legal system. Illegal immigration responds to economic signals in ways that legal immigration does not. Illegal migrants tend to arrive in larger numbers when the U.S. economy is booming and move to regions where job growth is strong. Legal immigration, in contrast, is subject to bureaucratic delays, which tend to disassociate legal inflows from U.S. labor-market conditions. The lengthy visa application process requires employers to plan their hiring far in advance. Once here, guest workers cannot easily move between jobs, limiting their benefit to the U.S. economy.
