Re: The other Pakis
College is not the be all and end all. But even if it were, all the religious folks I have known have emphasized education over all else, including "fun" activities. In fact, many kids in Pakistan and even some here were forced to stay at home and study while their peers were dating, partying. And some of the most intelligent kids I have known have been from religious parents who were "myopic" as you call them. I think low income has more to do with it than religion, and if that is the case, then yes that's a huge problem.
As for good paki and bad gora phenomenon, it goes both ways. You must remember elementary school all the way up to high school. You may not have faced any discrimination but kids are cruel, cruel about stereotypes that are not even exhibited in their target, such as BO and oiled hair. That fosters introversion and sticking to your own kind.
Maybe what people need to do is give oppurtunities to poor kids so that they do not choose the easiest way to earn money, such as driving a cab because education is expensive. And what maybe needs to be done is build tolerance in "bad whites", rather than attacking those stupid pakis. And of course, self-esteem building.
