Islamic socialism is a very important term these days in Islamic Finanacing system often associated with ZAB http://en.wikipedia.org/wiki/Islamic_socialism which attempts to bring a balance between free market and state-controlled economy. When ZAB in his first term nationalized the major institutes of Pakistan he didn't put ban on owning personal wealth or initiating private businiess. Some experts argue that, has he been given chance for some more years thr fruits of his policies would have been surfaced more effectively for the benefit of common people.
As far as labour unions are concerned I would agree with you that the labour unions actually slowed the efficiency of institutions, but this is only one side of story. Before labour unions at the cost of labour unions the owners of such departments, industries and factories were looting all the profit. But I don't buy this same mentality of our former masters (angraiz sarkar) and military rulers which believed that the people of sub-continent do not deserve Demoracy or they are not fit to enjoy basic human rights which westerners are enjoying. So I would prefer to give the due rights to labours as well as make sure that the intrets of institution and owner are not compromised. It is fundamental right of labours to form a union and have their collective say. If this has failed in PIA it has been greatly successful in PTCL, OGDC, WAPDA etc.
About Mohtarma's cases in foreign countries I tried to respond it when I said "I can't rule out the possiblity of Mohtarma and AZ being personally involved in corruption...but who is not?"
Just in 18 month and 23 month old governments of PPP made its contribution in every sector for social welfare, Education (Increased budget for very first time), Health (Lady health workers program, polio vaccine, ), Economy (fastest GDP growth 6.76%), Transport (Indus highway), Defence (Missile, submarines, tanks), law & order (Karachi riots), Media (FM Stations, NTM/STN) and many more. You don't want to value them its your choice, but people do and that's why they have voted 4th time for PPP. I would challenge you to bring similar projects if at all carried by any other government of Pakistan!
