They can perceive all they want, I or anyone sane is not compelled to accept their delusions. They can believe the Earth is flat, the moon is made of cheese. Saying that doesn't make it so.
They receive much more in funding then they pay to the exchequer. They bitch and moan about "our stolen wealth" not understanding the difference between potential wealth (what is physically in the ground) with realized revenue (what is actually extracted, brought to market, and converted into cash).
They have a lot of the former precious little of the latter.
When dumbass nationalists claim "billions of dollars of wealth are being stolen," they look only at the alleged maeket value of the commodity. They arent smart enough to appreciate operating expenses, equipment costs, and decades of infrastructure building required to get that commodity out of the ground. WIthoit which "they natural wealth" is just useles rocks and dirt.
The already fucked themselves in the ass once. Over natural gas and demanding "market value", they priced Balochistan's gas out of the market. After all domestic gas at international market rates, means it loses its primary economic utility which is providing a cheap, competitive advantage to local industries. Hat happned instdad is that massive terminal at Port Qasim were built, and thar coal was utilised instead. And Baloch lost leverage. It went from essential to just another small mix.
