Sangom,
You overestimate the importance of Wallmart. Just because they could lobby here it does not make them representative of U.S interests. In fact they are in trouble in U.S for the lobbying.
I do not know how investment in retail trade would siphon off money from India. I have been listening to one too many bearded people on TV comparing Wallmart to East India Company and what not. The antipathy of our Communists towards U.S is well known. That clouds their views.
The Indian consumer market is very strange and extremely price conscious. Many American and European companies which came here expecting to reap a windfall have incurred huge losses. I know of one company personally. Henkel India. The other well known company is Whirlpool.
Wallmart has to compete against our small retail shops. What is called Kirana shops. They have the ability to sell below the M.R.P. They have no employee cost, their overheads are very low, and they pay very little or no tax. Of course they will never accept that they are making a profit, because then they have to pay tax.
They will not only give Wallmart a run for its money, but also beat them. Wallmart will be like the Malls and shops like Big bazaar, Spencers who cater only to a particular segment of the population.
I have seen this happening in Madras. Even after Spencers opened outlets in Anna Nagar and Numgambakkam , 3 to 4 new provision shops opened in Nungamabakkam and they are doing well. I can personally vouchsafe this because I was a resident of Nungambakkam. They offer personal service. One of the shops had me compare prices with Spencers. All the items were cheaper.
Wallmart is bigger. May be they can get a bigger discount on articles than Spencer. But they have overheads and employee costs. And they have to pay tax.
Though the Mom and Pop stores have almost disappeared in U.S our Gujarathi community seems to be doing pretty well inn running shops. They even defied the Mafia.
We the Indians are the greatest traders of the world.
More than the small traders it is the middle men who are behind the agitation against FDI. These middlemen are not even known to the public. They only deliver goods and make money. And they are politically powerful. They would be affected by Wallmart.
