Within the PoS economic sphere, the poor ones who find themselves
trapped in its unequal system will escape from it one by one.
There is an incentive to go fetch the poorer and stupid people.
There is no incentive for the outsiders to intervene in this unequal system.

Now I’m going to summarize the points so far. POS system is certainly the ‘Ponzi Scheme’.
