The avantage that the upper class has had on us for the last 10,000 years is connectivity. They have a small world network, we don't.

No system of government is capable of addressing this problem. If we put everybody into a small-world network, then we move to a one-class system. Still with differences in wealth and promenance, but without the ability for elites to form a conspiracy against everyone else.

Quick! Everybody make 50,000 local friends and 50,000 international friends! Then everybody will be either a friend or a friend of a friend. That will be the end of the upper class.
