CenVAT - What?

Mr. Common Man:I am a common man. I work for food, shelter and clothes. I don't understand why some bank going bankrupt in some part of the world should impact the price of my day to day commodity to increase. I get the rice supplied in ration shop @ Re.1/- per kg. However, the other ingredients that go with rice are sky rocketing.
When the crude oil prices were high, the petrol / diesel / LPG cylinder prices were increased, in order to control the lossess of the petroleum companies. When the crude oil prices went down to one third of their peak price, the petroleum companies stopped their productivity because they do not get enough profit margin. The prices were reduced, but, very minimal. There is an acute scarcity and restrictions on the availability of the domestic LPG cylinder.
Mr. Nut Case:Come on, Mr. Common Man - don't you know, the government had slashed the cenvat? Due to this the car prices will go down. The airlines will reduce their ticket price. Air India offers one free trip for every eight trips you make to selected cities. See, the government is giving you so many benefits and you still keep cribbing.
Mr. Common Man:Cenvat - What? Reduction in car price and air fare ... what does it mean to me?
Anybody ... any help ?
BTW, French Revolution was a history, isn't it?
