My patriot brother, let's just agree to disagree.Bro who told you rupee was artificially maintained for 7 decades?
The REER value of rupee never exceeded 110 (on the higher side) during musharraf or even ppp era. It was plmn tenure in which REER crossed 130 threshold for the first time, and opened the flood gates for BoP crisis.
Zimbabwe is printing those notes because of bankrupcy due to BoP crisis same as what you see now in Lebanon, or what happened in argentina. This is due to buying more stuff than you can afford. Artificially manipulated currency leads to BoP crisis to bankrupcy, and when the bubble bursts this is what happens.
You should be thankful that Pakistan contained its BoP crisis before it got out of hand otherwise you would be seeing a million pkr note.
