It comes down to whether you can make a living in India if you get into sports. The economics around it are strong enough to force out anyone considering sports. Cricket is the only sport in India that can get you top dollar whether you make it big or small. The compensation provided to a person playing hockey or table-tennis is meager in comparison.

Those that are talented and have the will + passion for the sport shine as long as they have enough funds. Then there are those [1] that have to sell their bow to make ends meet despite securing a silver medal at the south asian championships. It was heart breaking reading that.
