An economy is an infrastructure for growth similar to a garden. Economies need regulation (tending) just like a garden does.

Whilst establishing a civilisation we humans have made a choice to order our environment. So its is contradictory that some people advocate an unregulated economy.

A self-regulatory (untended)   garden (economy) will let unwanted plants prosper. Weeds will take over and the most useful plants and fruits die out in untended gardens.

The flipside is also true. A good gardener (economist) will not be heavy handed on pesticides. The garden ecosystem require spontaneous interaction between organisms.

“Market forces” is just another name for greed that must be constrained in a civilised society.

The garden is used as a comic metaphor in Being There.
The terms “Capitalism” and “Socialism” introduce ideological prejudices into viewpoints on money and equity .
