i dont know about accuracy of these numbers but to me it means that PPPP era there was a total of around 90% increase(11.5 to 19) vs total of around 60% increase in 4 years in PML era(19 to 31)
i doubt you can jump from 31 to 40 in a year not possible
However , I personally feel it is best that we keep our existing budget to 5 Billion range for defence
The idea of randomly assigning $$$ figures across the board without tax collection does not seems logical, there is ample possibility of misallotment of finances as there would be no track record of where the funding is going
The Extra 4 Billion can be spent better on following
a) Hospitals 500 Milllion USD, indirect job creation(Nurse , Care takers, Doctors)
b) Grade 1 to Grade 9 School standard Improvements 500 Milllion USD (Teachers , laptops)
c) City Cleaning Projects or recreational grounds 500 Milllion USD, indirect job creation (Drivers for trucks , garbage collectors , workers in sanitation)
d) Improvment City wide Electrical Wiring 500 Million USD (Engineering jobs)
Alternatively 500 Million for Medicine production locally in Pakistan should also be a priority (Incentives for Local companies to make generic medication)
Fix Water / Hospital / School and Sanitation / Electrical Theft issue
4 Extra billion is a large amount of funding
** Improvement in salaries should come from Improved efficiency in Tax collection process
