This girl has a good idea, but is so incoherent that it gets lost somewhere. Let me try and rephrase what I think she is trying to say:
“The premise of democracy is utilitarianism. Citizens are defined equal so that the each utility function can be defined simply and aggregated. Introducing special benefits for a specific group, makes the overall utility function difficult to aggregate because of Arrow´s impossibility theorem, and so difficult to maximize. Trying to aggregate or maximize utility in spite of this impossibility leads to all kinds of dysfunction.
A thoughtful solution, unlike the first amendment, still preserving some kind of reservations, might lie in a wonderful short book by Amartya Sen called The standard of living.”
That is it. What is all this blather about tall and short students in the school? And why should Modi not get elected if the majority prefers him?
