Not going to happen in Pakistan even if dollar crashes. The economic growth rate is almost nil in real terms. Remittances are dwindling because of overseas Pakistanis also affected by the pandemic lock downs, loss of of business and employment.
Even if some miracle happens, the price decrease may be in the range of 10,000 to 30,000 max.
Really hard times ahead and our government is a clueless bunch of incompetent opportunists and job seekers.
