Its not like one need to have PHD to qualify for government job in Pakistan. Karachi have huge private sector jobs which it leech of from rest of Pakistan, see how many headquarters there are in Karachi of companies working all over Pakistan. This is why muhajirs are easily richest ethnicity in terms of per capita. Before you repeat your tax collection BS, its mostly through exports/imports which again 80% is from rest of Pakistan.
Crying for not getting 100% of government jobs in Sindh is getting old.
