Governments agree but they don't always fully deliver to the plan, that's normal and keep happening. You have to understand this, what IMF says is not wrong. It is absolutely correct. What IMF dictates is not wrong. They simply ask you to tax your people more in order to pay back their debt. Fair enough. However, IMF is a political tool i.e. often used to push around countries that need financial support, that bit is objectionable, nothing else. Also, IMF would never give you real things to fix. IMF would never say fix your electricity line losses, improve your collections. IMF would simply say, increase rate of electricity to pay us back more. (Counter productive as it kills economy) Hence fixing loss causing issues of state owned institutions is a big thing not small. If electricity is cheap, in future economy would boost because of it.
Another financial achievement of PTI, record tax collection.
Pakistan has lower per capita income than India. Although I'd say both sides have a lot of gap between rich and poor. The lower class of India won't be any better than Pakistan's lower class. However, measures like taxing fuel 100% hurt everyone and poor would be affected more than the rich although it is a great way to raise some money. Government should rather work on incremental tax system. Khan also talked about incremental taxation a lot. Tax rich more and spend on poor for an equitable growth of society. However in today's society and financial system, its easier said than done. Wealth is held in the hands of a few. This is a capitalistic economic system. If you try to tax them, they are able to punish governments in pain staking ways. Wealthy elites have their influence on stock market, market associations, media etc, everywhere. You try to get money out of them, they turn against you. Eg. if Modi tries to tax Ambani, Ambani would pack up his factories and take them to Nepal/Bangladesh or anywhere else where he would have to pay lower taxes and make more profits. For any politician doing the right thing is very difficult.
Pakistan needs to fix loss making institutions. Gas, water, electricity - 3 inputs for any industry. These institutions should be self sustained, non-loss making. And per unit price of their production should be low for publics to pay. Pakistan needs to industrialise and grow its exports. Pakistan needs to recover income tax and GST on all sales. Pakistan's collections are very low. Despite the fact Khan collected record tax. It is said that some less than 1% people pay income tax in Pakistan. Controlling corruption is also very very important. Pulling money out of real estate and investing it in industry is also very important. Khan needed majority government for a lot of this. He was handicapped to begin with.
