"The flow of Mexicans to the north can be strategically contained either by improving the quality of Mexican economic life, or by suppressing opportunities in U.S. life.

Congress could pass a law imposing huge fines on any American enterprise that hires illegal workers. Collateral pressures could be applied, involving driving licenses, hospitals, schools. Are we willing to adopt such measures?" Can We Stop Illegals?, April 8, 2005Mexican states differ rather markedly in their tendency to produce migrants and to accept migrants internally. Furthermore, claiming that just because the PRI or PAN can't improve opportunities in Mexico, it can't be done is showing a rather extreme lack of imagination or willingness to investigate—and frankly has twinges of racism attached to it.

If the US tax and regulatory structure is such that it mandates use of illegal aliens, that should be fixed.
But it won't be until the law is taken seriously by those that have benefited the most from it.
