The Idea of Free Lunch

Kartikey Sehgal
[Milton Friedman in his book 'There's No Such Thing As a Free Lunch' says that ". . . every bit of pork, every subsidy, every inflation, every politically-imposed inefficiency, is paid for, and paid for in full -- by somebody."]
The traffic cop stops a citizen and complains that his vehicle is emitting dangerous amount of pollutants. The driver shows the sticker to the cop and exits from the situation. That sticker was purchased for 100 Rs from a government official who checks vehicle maintenance. The true cost of the sticker is 1000 Rs. By bribing the government official, the driver saved 900 Rs with which he made his children happy.
This is free lunch for the driver.
