Re: Sindh Through Centuries!
First of all thanks for such a detailed post and starting an interactive session in this thread. You are definitely in right thread, because just posting some pieces of rich history of Sindh is not my purpose. I myself is learning and when people like you contribute raise questions, I’ll be able to learn more to make this thread ‘Paisa wasool’.
Coming to your questions, its a natural phenomenon in any nation’s history to see a fall, where it feels like there is no agitation against the atrocities.
I agree your point about the general attitude of Sindhi society towards education. But you can understand this situation if you look at 19th Century India, where Sir Syed Ahmed Khan had to make lot of efforts to promote need of modern education in Muslims. Before partition in 1947, Sindhi Hindus were dominating education sector in Sindh. They built schools and most of teachers were Hindus. Sindhi Muslims have the same attitude towards education as Muslims in other parts of the united India. At the time of partitions, Sindh’s literacy rate was higher in areas forming Pakistan (some statistics says it 5 times higher than other areas). When Hindu population was made to migrate, the schools they ran became deserted. Then came a blow, when many Sindhi medium schools were closed across the province (Sindhi was medium of instruction in all the institution upto college university level). While Sindhi Hindus who migrated to India, built schools in Bombay, Gujrat within months (management of D J Sindh College Karachi was able to built Jai Hind College Bombay within 4 months after their migration to India), Sindhis in Pakistan had to face shortage of teachers coupled with their general attitude towards education.
The situation became worst when education institutes were politicized. I don’t say that students shouldn’t be involve or at least be aware of current affairs, but the kind of politics that prevailed in Sindh’s education institutes (which I myself observed in 1990s) was limited to boycotts of classes. These politically motivated students (locally known as comrades) use to close down primary schools every other day after they boycotted their classes in college.
This all contributed towards destruction of education system which also intensified due to booti maafia. I remember the problem, when I didn’t took booti with myself and invigilators coming to ask me ‘have you completed that question. If done, give us the kartoos (micro-notes) to provide to someone needy’. I do remember listening to students in Islamiyat paper (requiring to write a note on Risaalat), ‘falan mujhe Risaalat (note on Risaalat) de’ 
So Sindhi society did destroyed its education system, coupled with no interest from the authorities and ministers who didn’t think it as necessary. They actually used it for their political mileage. As you gave example of Oxford graduate PM, he did opened schools, gave grants to Sindh university, but there was no emergency for primary education. I don’t want to be suspicious about Mr Bhutto’s intention after reading his interest in improving Sindh university in Shaikh Ayaz’s book, but it appears that these politicians have never been interested to bring changes at gross root level. Primary education is facing more problems in Sindh, though today we got a private school in each street, but affordability still remain the problem for many parents. My chacha decided to withdraw his intelligent daughter from a private school and admitted her in government school (he himself is a teacher, but he had to take this decision due to financial problems and education expense of other children). The quality of government schools has deteriorated in recent years. I myself got education from government schools and college from rural Sindh and I had no difficulty to pursue my professional education in Karachi. But I don’t think so that government schools are providing that quality education now.
These are some problems that have resulted decline of literacy rate in Sindh. Those who can afford send their children to private schools and those who can’t send their children to government schools. In recent years, after introduction of entry tests at university / medical colleges level, students now try to avoid booti source, which is a good sign, but a lot has to be done for primary education. May be Public-Private sponsorship can bring some changes alongwith the accountability of ghost schools and teachers. Recently, Sindhi media followed ghost teachers and many lost their jobs. A good sign, I would say and it should be done to mega level.
In respect of your question about book reading, I saw an interest in Sindhi youth to show their presence at book fairs, festivals related to history and literature. Its a good sign. Apart from Sindhi news channels have started highlighting the works of intellectuals, which will also contribute to the society. As you mentioned that every part of Pakistan is proud of their history and culture (and it should be, I’m all for it), having media sources in your mother tongue do have an impact on society. I really admire Sindhi intellectuals who stood for their language and now we have dozen of Sindhi dailies and around 10-12 TV channels to create awareness among those who can’t understand other languages properly. My own Mom can understand Urdu, but she can’t speak that, so her source of information is KTN News most of the times 
About your question, whether Sindhis will accept a non-Sindhi their revolutionary leader, I would take you to history of Sufis in Sindh. Who was Qalandar Shahbaz by birth? He migrated from Marwand (Afghanistan) and now he is SindhRi da shahbaz. Who was Shah Latif Bhitai? His ancestors migrated frome Hiraat (Afghanistan). Now Latif is Sindh and Sindh is Latif. So, there is a tendency in Sindhi society to accept outsiders as their leaders / role models if their concern for mistrust is addressed. Look at Sindhi media’s coverage of Imran Khan’s jalsa in LaRkana. They highlighted it when he announced his dissent over controversial issues of Division of Sindh and Kala Bagh dam.
