Great logic. You are telling me forex reserves is the only way to build Metros ?
Next time keep BOT (Build Operate Transfer), Investments, and loans in mind before you open your mouth.
When did i compare Pakistan with London huh ? I know you are ignorant but let me remind you that i compared London with Canadian cities (so called 'developed')
Now that you mentioned Pakistan let me just say you should be embarrassed by the fact that Karachi is the only mega city in the world without a Metro. Even countries like Egypt, Columbia, North Korea, Mexico, Thailand, Ukraine, Uzbekistan, and Chile have metro systems. Last time i checked, sanctioned Iran is expanding and Bangladesh is preparing to start its first...
Transportation systems are a blessing. Not only do they help people reach from point A to point B, they create Jobs, save money, save fuel costs, and also boost real estate market in many areas.
