From what I have read, till now, in this thread is:
Capitalism seems to be way to use our dormant populace , changing , by way of investment in education & health , into a productive asset .
As we have more population, so by channelizing them, we can have greater rate of growth.
But, the question is : Will it be sustainable?
Sustainability,usually, have three aspects:
1. Economic
2. Social
3. Environmental.
First, Economic : It would not only be sustainable , but also highly profitable , if we can follow the "export model" of growth , of our Indian talent , like Teacher/Nurse.
Second, Social : I think here, we would fail , as "greed" basis of animal spirit of capitalism , is something we detest culturally. So continuance investment , a prerequisite of Capitalism, might not be fulfilled.
So , a western model of capitalism, can proved to be beneficial to us, but on the same hand , may not be totally adoptable to society.
