Apparently there's a lot of opportunity in Texas, and more than 100,000 degenerates belong to street gangs which have allied with the Mexican cartels as reported by Mike Glenn for the Houston Chronicle:
The Mexican cartels have taken over the methamphetamine trade and are establishing connections with local gangs. But, the gangs also take part in cartel-run human smuggling and trafficking rings, which often includes forcing adults and minors into prostitution. Gang members guard stash houses where people who have been smuggled into the country are held for ransom.
Mexican narcos have taken over the criminal underworld on the Texas streets as "acts of love" for their impoverished families according to former Florida governor Jeb Bush, and no doubt in a generation or two their descendants will become American politicians. After all, behind every great political dynasty is a sordid historical felony.
