Many (most?) Latin American illegal immigrants work hard and efficiently. They live in run-down apartments two to a bed room with several sleeping in the living room. This is the life of most US immigrants, Asian, Latin, Easter European, African, legal or illegal, irrespective of origin. You see them everywhere performing landscaping jobs, car washes, other types of menial jobs. They work in the restaurants, warehouses, hotels. (And yet, after a lifetime of hard work, they own homes, businesses and send their kids to college, go figure.)
Many middle class white kids have only experienced a life of indulgence and are dreadfully unprepared to survive. Whose fault is that? Typically in their first job, they perform miserably, especially compared to hard working Latins, who show up to work every day, on time, not hung-over. So which choice is an employer to make in an industry that depends on labor? English speaking, sloppy and recacitrant, or Spanish speaking, attentive and go-getter?
The most salutory experience for a middle class kid in his first job is to be fired within a week for poor performance. Your Chipoltee problem is poor line management, and the temporary disruption of bringing on a large number of inexperienced workers on at one time. Nothing else. It will work itself out in a couple of weeks and you will not see half of the present workforce.
