We should invade the northern part and declare a new border somewhere north of Mexico City. We then sponsor an independent northern Mexico state, hang the drug smugglers and install a U.S. friendly government.
Most of the best Mexicans I've met in my life come from the entrepreneurial north of the country, especially around Monterrey. Car assembly plants designated for the U.S. market are also located that general area. Mexico City and southward are mostly populated by the indolent and government bureaucrat parasites who live off bribes and taxes.
I like that idea!
