Present system is not good enough

I believe that the idea of democracy that came up, say, more prevalently in the 18th century and then was implemented with the American Constitution and so forth.

I think that in 500 years or so people will look back and say, how could people have been so stupid to think that a democracy would work? Because everybody wants to take as much as he can from the cake and through the voting machine and through all kinds of tricks and so forth, the politicians always promise more than they can deliver. If they tell the people the truth they're not going to be elected. So I'm very pessimistic about the present system.
