Sir your previous write up on Golden rice also was very informative. the fact is our country (india) Politicians are not well educated or informed to understand basic economics and business models of pricing. For example it is not just drugs even Diesel/Petrol tax is as high as 42% of the end price of Rs74 in the state of tamilnadu. This tax includes 27% vat(state tax), and another 20% Excise duty(federal tax.)
