Disobey has it backwards. Capitalism is the natural state of economic interaction. What is evil is socialism to a varying degree depending on the form it takes.
Capitalism in its most basic form is each person performing tasks and producing things that they want in excess of what they, themselves, need. That excess is then traded to others to accumulate wealth, or stuff, that makes them increasingly productive. In a capitalist economy, people can voluntarily pool their wealth and abilities to create a greater amount of output with value that can be used or traded. For those that have less or cannot provide for themselves, each individual with wealth decides what they might give. That is the basis of charity.
With socialism, or its more virulent cousin communism,
human nature is denied in favor of forced contribution. In such a system you receive a base amount of goods, services, and wealth regardless of your input. Anything in excess of that can, to one degree or another, be taken by society to provide for those that don't produce. In a nutshell, socialism is forced altruism. That is, society expects you to work hard but willing give up the fruits of your labor to others in whole or part regardless of how slovenly and lazy those receiving it are.
It is criminally evil to forcibly rob the rich to give to the poor. Or, put another way steal the fruits of one man's labor to provide for another man who puts little or no effort in to his own welfare.
To make such a system work requires an increasingly authoritarian and dictatorial government to take from the productive to give to the unproductive. Charity dies in such a system as does any work ethic. Why work hard when it will just be stolen from you? Such systems also encourage by their actions cheating by those living in them.
There is nothing noble or just about socialism. It is an evil system designed to enrich the undeserving at the expense of the productive.
