Communism

Organized predation of the few by the many

In which the few either disengage (perhaps by flight) or are consumed, leading to expand "the few" to include new members and continue the predation. Eventually either reverts to ordinary statism (predation of the many by the few) or runs out of victims and collapses (or both).

“The problem with socialism is that you eventually run out of other people's money.”

-Margaret Thatcher
