From the Toronto Star November 11, 2007 artcle "Picking through Pakistan’s cliches" by Haroo Siddiqui an answer to my question.
"The larger question is: Why has democracy floundered in Pakistan but flowered in India?
The British, favouring India, had left Pakistan with an empty treasury and no infrastructure. That made Pakistan that much more susceptible to American development and military aid in the 1950s.
Whereas India abolished the feudal system, Pakistan retained it, allowing the landed gentry to team up with the military and the bureaucratic elite to take turns ruling the state."
