Your PPP per capita , wealth per capita is way behind . Your middle class as % is also lesser than ours . you should probably read more about economy as its growing at 5.3 % for 2016 .
As for corrupt politicans well you shouldn't be talking about that because Bangaldesh was at one point ranked the most corrupt country in the world . It still is way more corrupt than Pakistan in corruption rankings . Meanwhile your corruption score is stagnant we have been constantly improving our score .

Pakistan ranked 116 while BD is at 145 .
Do you understand GDP/capita?
Pakistan has 2% populatin growth and so 5% GDP growth is 3% GDP/capita growth.
BD has 1% population growth and so it's 7% GDP growth is 6% GDP/capita growth.
When measuring how a country's population is becoming wealthier we need look at GDP/capita growth and not GDP growth.
As for the quality of politicians between Pakistan and BD, Pakistani politicians delivered 3.5% GDP capita growth rate during the 1980s(best since independence) to it's people while BD politicians delivered 5% last decade and 6% so far this decade. So which country has the better politicians here? At the end of the day all that matters is the economy and everything else flows from that.
I do wish Pakistan luck but am not that hopeful as it's economic has not grown really fast since 1947. Too many people are pinning all their hopes on CPEC. CPEC will build Pakistan's infrastructure but other things like law and order, education and sound economic policies need to be put in place and this will be challenging to implement in Pakistan.
