Which is exactly what I'm talking about. Communism = "for sufficient power to influence/accomplish a goal, you must be in the party elite (tens, at most hundreds of persons)". Liberal democracy: "for sufficient power to influence/accomplish a goal, you must start at least reasonably well off" (3 to 4 orders of magnitude more people)

"power" is distributed in democracies; The centralized nature of communism is its weakest spot, and it is by design.
