One more point: many people say that currently the rich people become richer, the poor become poorer, and the middle class disappears.

It seems to me that the language used to allow greater equality among sectors of society at a certain point ironically became simultaneously both a prison and tool of that power struggle in it's own right. It's just more slop for the pigs to fuel the idea that our soul is on it's way to meet us somewhere else, but it's always standing us up when we get there. The best you get is to feel good about what you have and rest comfortable it's more than someone else has; this is the main comfort of the purely natural way of life.
