An alternative is asking if there is an alternative way to seek $10 billion a year in investment from the diaspora and finding our what their demands would be (beyond just elections). It could be a virtuous cycle, where the profits are not withdrawn from the country but reinvest over and over again. This also does not prevent GCC investment, but gives the Pakistani government more leverage to negotiate better terms for the investment they want to make, such as instead of PIA being completely sold off, it could be made a partner budget airline of a GCC carrier like Qatar Airways.
It also doesn’t have to be rocket science. Overseas Pakistani investing in their own agricultural land to increase crop yields, or buying out IPPs to renegotiate power prices and being compensated by the government with land in desirable places to form residential apartment blocks in a walkable, clean, lively, and secure neighborhood (something like Barcelona and not massive skyscrapers).
