It's an interesting question in relation to blockchains because there is such a small barrier to create and migrate to another system.
If there are only people with the money ruling, the creators and the other people who add the value may leave for an alternative platform. What are the rulers left ruling? Are they too rigid to change?
Some sort of balance needs to prevail and for that reason the most adaptable may be better suited to survival, the ones that can help the system reach an equilibrium.
The money rulers still get to rule, it's not like they are going to be giving away their money to reach an equilibrium hehe.
