Maybe not do a 126 day long dharna causing Pakistan 2% in GDP? How about not promising paradise and shrinking Pakistan's GDP by $35 billion in just his first 8 months? Or, not punch Pakistan's GDP Growth Rate to 2.7% from 5%?
And why move on? Why not simply get lost and let the experienced run the country which had significantly improved in just short 5-years.
There has been no improvement.
Balochistan is a hotbed for separatist activity and along with KPK, Southern Punjab, Interior Sindh, are decaying in poverty. Karachi is literally a trash bin. PML-N literally lied about building the Western CPEC route and by doing so, aided India in replicating the process in which they tear Pakistan apart on ethnic lines - just like Fall of Dhaka. Had Qamar Bajwa not pushed for FATA to be merged to KPK, PML-N was deliberately stopping that, even though that was the explosive powder PTM was using to incubate separatism in KPK. Thankfully, they merged FATA and PTM died out instantly.
The only improvement you had was building roads through the Eastern CPEC route, that really weren't necessary, as the region is already linked up with enough road/rail network. Maybe a few power plants to generate more electricity, but are still useless because they forgot to upgrade the British-era power transmission lines.
Thanks to PML-N borrowing loans to artificially prop up rupee which ended up subsidizing imports and taxing your exports, even worsening their competitiveness against other countries, your country has been successfully de-industrialized.
Numbers are garbage, even Musharraf's government boasted better numbers than this. But as we've seen before, unless your country has a vibrant private industry that sustains a strong manufacturing base, that import & investment-led economic growth dries up faster than water drops in a desert.
I'm not fan of PTI's economic policy. I believe Imran Khan should replace all of his economic team. However, to say that PML-N had a glorious and prosperous rule is not correct. All of the governments, PTI, PML-N, PPP, PML-Q have done a poor job in running this country. That's why Pakistan has had to go to the IMF repeatedly.
