When we were young kids growing up in America, we were told to eat our vegetables at dinner and not to leave them. Mothers said, "Think of the starving children in India and finish the dinner."
And now I tell my children: "Finish your maths homework. Think of the children in India who would make you starve, if you don't."
-Thomas Friedman in "The World Is Flat"
