That's if you don't count the money they send home to Mexico that they receive from welfare, from the food stamps that they sell for cash, and from the money that they save by living 10 to an apartment, a violation of most city's zoning laws. And do you think that maybe at least a few Mexicans may engage in criminal activity such as selling drugs to bring in some money?
Oh yes, some surely do, and I'm sure you agree it is terribly embarrassing that such an overwhelming number of white Americans lust for illicit drugs.
Pesky markets.
