I don't support the government - in fact, I hate PPP - but you should try reading the newspaper once in a while. Prices in almost every country that relies on imported oil have increased by up to 15%
Now either the governments of like 10 countries are corrupt. OR the government actually has no other way to raise money.
As for the 'not everyone can afford petrol at skyrocketting prices like you" comment ... I too, have been affected a lot by the increases. But instead of abusing the government, I try to save petrol and travel less instead.
