Exit, Shortest Version

What can become a parasite class will become a parasite class.
Any government without exit can become a parasite class.
Parasite classes raise their costs above their benefits.
Rebellion will come to have a higher expected value than submission, even accounting for loss aversion.
The parasite class will collapse.

Unless parasitism per se is attacked, in other words unless Exit is enshrined and sacralized, the cycle will repeat.
