Nope not every thing is imported. Many car parts are made in Pakistan but car manufactures don't give contracts to local producers and import stuff now they will give contracts to local producers. People will buy less clothes from Gucci and Armani and buy more that are produced in Pakistan. People will buy less Iphone and buy more Q mobile
There is a huge list of stuff. This is good for economy.
In the international market Pakistani goods will be cheap now and thus will give more competition to other goods Exports will go up.
Bad new for those who prefer luxury life good news for a common man. Bad news for those who buy dollars and keep them in international banks and good news for those who bring money to Pakistan.
