Yes that is the only area government performed bad but other parametes were good like:
GDP increased from 3.5 to 6
Inflation reduced from 9.4 to 4.8
foreign currency reserves increased from 9 Billion to 20 Billion
Tax collection doubled in five year (every year increased 20%)
stock market from 32000 to 53000 (at day before Nawaz disqualification)
Entire world was praising Pakistan's economy with leading financial newspaper writing on it.
1. GDP was 5.2, not 6. and that also consumption based, not sustainable, just relying on loans, as soon you start paying back loans, it will crash.
2. Inflation was about 5 in may 2013 and 11 in Nov 2013.
3. Foreign reserves were about 8/9 billions when PMLN left the Govt.
4. Tax collection was doubled using massive import duties on imports, denying refunds to the bizs which eventually destroyed pak's economy and exports.
5. Stock market was around 40K when PMLN left the Govt.
6. Entire world was praising, but at the end of PMLN Govt, Pakistan had only reserves for 2-3 weeks imports and at the verge of collapse and begging to IMF for another package.
