I had one student at a bilingual school in Mexico, who after being at this school and supposedly learning English for 5+ years, still couldn't speak it and barely tried to make any effort to learn anything. Didn't do assignments and failed almost every test. When we mentioned it to her parents, their attitude was that she doesn't really need it because she will just marry someone who will take care of everything for her. My thought was, "Who would want to marry someone who doesn't know anything and makes no effort?"
