Inter related things.Ferociousness here is due to frustration of too many people around. Too many people means: Too much inequality,inability of governing people properly,lack of regulations and so on..... India is 3 times more populated than USA but 1/3 in land size of USA! Population does matter. Nothing about riches only in India. Put these conditions in any other country and you will see same behavior.
