One Does Not Know How to Begin

According to Peter Frase:

Frase's Four Futures are:

1. Communism ("equality and abundance")
2. Rentism ("hierarchy and abundance")
3. Socialism ("equality and scarcity")
4. Exterminism ("hierarchy and scarcity")

How's that again?

There are two possible confusions here:

• A possible confusion between effects and causes: If we have both equality and abundance, that it likely to produce the society on the label of communism.
• A possible confusion between allowed hierarchy and permitted hierarchy. There is a difference between a “hierarchy” produced by people of differing abilities and a hierarchy produced by people of differing amounts of pull.

I specified “possible” above because I have not yet read the book in question. Maybe the author drew those distinctions.
