This I have taken from The Tribune written by Khushwant Singh the link is :-
DR Farrukh Saleem, a freelance Pakistani journalist based in Islamabad, wrote an article comparing India's rich with those of Pakistan. It was published in September, 2007. Amir Tuteja, based in Washington, sent me a copy. I quote a few excerpts: "The two Ambani brothers can buy 100 per cent of every company listed on the Karachi Stock Exchange (KSE) and would still be left with $30 billion to spare. The four richest Indians can buy up all goods and services produced over a year by 169 million Pakistanis and still be left with $ 60 billion to spare. The four richest Indians are now richer than the 40 richest Chinese.
