Even here the problem goes back to the mullah class. In UK it is quite disturbing to see the British-Paks have some of the lowest educational indicators - in fact we are lumped with Blacks and almost at the bottom. The Indians and Chinese conversely are right at the top and above the indigenous English. So what gives? We have to exclude discimination as Indians are brown or often even browner then Pakistani's.One word: Illiteracy
Well, part of the reason is mullahs hold on the British-Pak demographic. As @Azadkashmir will confirm driving through Pakistani areas in UK will be struck by the number of mosques/madaris which have sprouted everywhere. After school you will see lines of Brit-Pak kids [often wearing Arab style gowns - perversly they were born in UK to Pakistani parents and now have converted to being pseudo-Arabs] walking to the local dars to be indoctrinated by the local mullah. The vast effort, time and money invested in this by the community if even half of it was pushed into secular education these kids would quickly rise to even beat the Chinese or Indians.
When after school the Indian/Chinese kids are being taught finer points of calculus mathematics our kids are being taught if swallowing your spit negates fasting. Specifically in Pakistan consider the number of madaris and the bast numbers of children being brainwashed there. If all that effort was used to teach modern education it would produce a generation of engineers, doctors etc and the country would not need to imprt Chinese to design or build their motorways or dams.
