It doesn't work that way as you might think sitting in Arizona. Suspending all development of advanced technology till the "poor" were taken care of, which was Gandhi's (good) intention, would never have worked - India has Islamic countries on either side and a Communist country hungry for resources on the north, not to mention Russia very close by. In the 60s and 70s, Indian scientists traveled to UK, US and Europe to beg, borrow and steal nuclear technology, and also started an effort internally, which is one the reasons the country has not been wiped out or invaded by its neighbors. The use of advanced technology has been mocked forever - when I was a student, it was proposed that no college degree should be awarded unless the student explained his studies to the farmers in their local language. But going the opposite way has ensured wireless connectivity for the masses, millions of software jobs for domestic or outsourced demand, enormous foreign investment, an enormous increase in the status of women and low-caste people, and a slow eroding of religion and superstition barriers. Otherwise, India would be a slave country now.
Sometimes trickle down is the only way. India did not start from scratch like the US with tons of natural resources and no baggage.
