Why does power corrupt communism?
Power, especially absolute or unchecked power, corrupts all
forms of government, because all governments are run by human
beings, who are inherently flawed and will naturally try to
arrogate more power to themselves, even if they believe they are
serving the people and the greater good. Communism, either as an
economic model or a system of government, is inherently flawed in
ways that have little to do with the exercise of power.
