An education system more like England would be very effective for India. It will improve their English abilities which will keep them the world leader in call centers. It will improve their call center ability to the point that all call centers will be there. This idea is an outstanding idea.
I believe it is generally folly for a country to adopt any custom from a country that is radically different than their own simply to try to make things better. India is a unique country with a plethora of unique needs. Its leaders should look at all education systems before deciding which elements, if any, to incorporate into their own education system.
