The generational leap that aircrafts have taken and the price they command looks big, but if compare to the general growth in GDP, its actually not that bad. Imagine an F16 that was sold a 14 Million and compare it to the most recent ones offered to Pakistan.

Today a f16 that PAF wants stands at about $87 million. Also factor in the fact that in 1988 1 USD was equal to 20pkr compared to 100 PKR today.
So an aircraft PAF bought back in the 80 costed them About 20x14Mill PKR, today it would cost Pakistan 100*87mil Pkr. that is a 31 times the cost that it needs to procure the aircraft it wants/
Also understand that Pakistan's gdp is almost 5 times that it was back in the late 80's , so the fact of the matter is at 87million dollars per aircraft, the aircraft is almost 31 times the cost of a similar scenario back in the late 80's.
Aircrafts are 31 times the late 80's cost, your economy is at 5 times the late 80's and that remains the issue.
