Subsidy to rich on Petrol

I wish Mamta Banerjee all the best. But still writers Building is one year away and need hardwork to achieve target. It is sad, that she don't understand economics, otherwise why she is opposing price rise of Petrol, which is used by rich people. If Govt of India is paying subsidy on Petrol. This subsidy is going to rich people, the money of poor and rural people going into the pockets of rich people.
