There are always many sides of the coin. But we have a tendency to look at the uglier side only.
Since you have raised a question on the taxes on Petrol, let me remind you that the price of petrol was increased to 45 - 50 when crude oil was at around 60 dollars per barrel in the world markets. And now the crude oil is cruising at 120 dollars per barrel. Have you ever seen that side of the coin, which the same goverment, same system, same policies had brought in for you.
But then may be some times blaming other relieves us from some tensions. Cheer up guys. We do live in a happy world. And for the things that are not good, we only will need to improve them.
