Why do I subscribe to Outlook? I can collect news and views on my own, perhaps through surfing the Net. The answer is obvious. Outlook is more efficient at doing this than I am. My time is spent more productively elsewhere and everyone gains from this specialisation. Why isn’t there a law that decrees that everything consumed in Delhi must be produced in Delhi? Surely, Delhi should strive for self-reliance. The answer is welfare gains from specialisation again.
Sadly, people see red the moment national boundaries—at best artificial and irrelevant for economic rationality—are brought in. Self-reliance for Delhi is stupid but self-reliance for the country is good.
