Let me cite, as an example, the husband of my friend's sister. He never finished HS. His job skill was limited to being a driver in the Philippines. He tried his luck in the middle east where he found limited success in sales but because of poor guidance during his formative years, found himself in bad company & was imprisoned for a drug related offense. He was deported back the Philippines but was never able to get any decent job. He now spends his time asking for dole outs, duping anyone he knows for some cash & to top it all up, spends a great deal of that money gambling online. You see, education is not all about pluses & minuses, it's also about right & wrong & shaping a person into a decent, useful citizen of society.

I read that article mentioned by chua_riwap. As I understand it, the reason for the choice of PUP is because they are highly trainable, not as ambitious as those from the more prominent schools, are not as salary concious & not know it all types.
