Oil became game changer only for a few tiny countries, like those in Gulf or Brunei. But look at the big country oil producer. Nigeria, Russia, Venezuela, Angola, Iran. For all of them, oil turned into curse. If vast oil reserve really discovered in Pakistan, it will most probably turn them into another Nigeria. It will make them to shelve their much needed economic reform and continue to spend recklessly, only to find more economic trouble in later date.
And for Bangladesh, yes I also do not like finding oil. We need to take the harder path for development. Not the easy one.
