Greed, money worship, etc. is not a product of the free market, but of sinful human nature. The mechanism to fix it is a circumcised heart. It is not money Paul says is a sin, but love of money.
Now the overseer is to be above reproach, faithful to his wife, temperate, self-controlled, respectable, hospitable, able to teach, not given to drubkenness, not violent but gentle, not quarrelsome, not a lover of money.
For the love of money is a root of all kinds of evil. Some people, eager for money, have wandered from the faith and pierced themselves with many griefs. (1 Timothy 3:2-3, 6:10)
Love of money is idolatry. Money cannot replace God as man’s security. Money will not do for you what the Son of Man has done. When Jesus tells the young man to give up his wealth on Earth and follow Him, He is ministering to him, He is telling him how to cast off his sin.
When Bernie Sanders decries love of money and “income inequality” in the same breath, your defenses should rise. The socialist does not want to circumcise your heart. He wants to stoke your greed and envy. He wants you to seek security in the wealth redistributed by the state. He wants you to depend on the predictable, guaranteed returns of economic planning, plans in which demand for existing goods and services is set by politicians and technocrats, forbidding the surprises of new knowledge from forming new industries, from creating new demand.
The theory of socialism is better than the reality. The principle of a system of universal sharing only works when social trust overpowers greed. For a populous, diverse country losing trust in its civic and social institutions like never before, as 21st century America is, it cannot work.
Economically, it cannot work. An apparatus has to do the sharing, that is, the taking and the giving. That apparatus is designed by flawed people who have prejudices and weaknesses. Because of their macroeconomic lenses, technocrats will only see what’s in front of them, the major industries like energy, cars, processed foods, personal technology, and online retailers like Google and Amazon. The “little guy,” where all innovations to better serve man gestate, is overlooked. When these huge, bureaucratized companies hit critical mass, they transition from an attitude of servicing customers to being served by customers, and they rely on the patronage and racketeering of socialists to get customers through the door to buy their stuff.
Socialism is the ultimate money worship. It signifies the fantasy of receiving without giving, nourishment by bread and wine without the communion. Socialism cannot heal the pestilence of greed and envy in our hearts. The free market, on the other hand, encourages risk and investment to the benefit of others before self.
