How do Indians make a living?

The Indian government does not provide employment to the masses of people living in India. The livelihood of the average people depends on simple needs of life. The average Indian (who has not inherited large properties) buys and sells vegetables. If he makes a little more money than his immediate needs, he buys a pushcart and sells more varieties of vegetables in bigger towns. He will try hard and earn little more by selling in more neighbourhoods. If he makes a little profit, he may rent a little room and convert it into a shop selling grains pulses, tea and soaps. Some Indians start a little tailoring unit; hiring a few persons, they make garments and market them. Some make leather goods like shoes or bags in a small factory. Some buy recycled plastics and mould new marketable items like chairs or shelves, on a small scale basis. With these small profits which they make,they can buy few food stuffs with  which they live. If large industries invade India, and if large retail shops offer items at lower rates, then these small businessmen will have no way of making a living.
With the state of the simple persons in India being so delicate, greater thought must go into making policy decisions in bringing in FDI (Foreign Direct Investment) which would encourage the growth of chain stores.
Lifestyle of consumerism has not hit India yet. People live life in a simple manner. Coming of large chain stores and advertising new lifestyles will bring in consumerism in a big way. This will alter our culture and way of life. What will the change in culture do to India? Do we want that change? These implications are never thought of. Capitalism and Western lifestyles are here and we cannot walk away from them. We continue being Indian and have already changed our economic outlooks. If this continues, what would future be like?
