All goods and services come basically from these two sources, either directly or indirectly:
1) The natural environment
2) Human labour.
Money, however, useful, even necessary as a means of exchange, produces nothing. Money does not work. People say "make your money work for you," but this is a metaphor mistaken for a reality.
Money, unlike humans and nature, does not work. Therefor, property and power accumulated through the possession of money, and not through one's labour or the free gift of nature is theft.
