One things to be considered of Allama Iqbal, Mohatma Gandhi, Mohammad Ali Jinnah Generation is that they had HIGH THINKING and Simple Living.
Nowadays people just showoff with their Mercedes, BMW's and think there some big fish in the country, this is todays standard.
Back then it was all Education based and simple living. I mean look Allama Iqbal even had a Library in his house, who would have such a room for books nowadays..
