Dr. Ramadoss is a visionary and yes, he is a qualified medical practitioner(though it is good for the people that he does not practice medicine). He is a visionary in the sense that he wants to take TN back to the dark ages. He expects everyone to buy substandard, poor quality stuff from the local shopkeepers!!!
He also does not realise that when big companies like Reliance enter the market, they buy directly from the farmer and remove the middlemen who, otherwise enjoy most of the profits. The DMK govt., in its earlier term started a similar scheme called 'Uzhavar Sandhai' where farmers themselves could sell their produce directly to the consumers. But that scheme failed miserably because the farmers were not good merchants and also could not take the time out to spend their time in the market rather than on their fields. Companies like Reliance emulate that scheme by buying directly from the farmers and thereby ensuring that they get a good price.
The benefits to the consumers needs no elaboration here.
Ultimately, no company run retailer can put the local Mom & Pop shop out of business. We cant run to these big chains for every small purchase and hence they only need to reinvent their business model.
As far as the TATA project goes, it is Titanium dioxide (a chemical) and not Titanium (a metal). A Dr. who is skipped his chemistry classes???
Dr.Ramadoss has never talked sense, so it would really be expecting too much from him on this issue as well.
