Bro you seem to not getting the point,let me simplify it for you to understand.
Every country has debt,but the debt % to GDP Is what you need to look at.pakistans debt to GDP is around 71.5 % that's the reason you need another loan to pay your previous loan,that's the reason your finance Minister is looking for another loan to present the budget.
To make it even simple,people using credit card have debt ,you can say everyone has debt ,but the difference is some pay the bills from what they earn ,that's the correct way but some who has spent over his means will default or pay the bills by taking another loan .Pakistan is on the second category.
