Natural men do not like the free market because it leaves everything to chance. Basic evolutionary theory postulates a universe of spontaneous change. “Survival of the fittest” at it’s core seems to indicate that man will take his chances and the “best” man or animal will win.
In a controlled or socialist society men who desire to act as God fight this by attempting to make everyone equal. That way there will be no “best” man to survive. These men play God in society because the don’t like the chance that they profess to believe in.
They are mistaken because as outline in Romans 1 they ignore God and try to overthrow the God that they know exists. These facts argue for a totally free market as explained by Gary North in The Dominion Covenant: Genesis (p. 10):
The operations of the market, like the operations of the atom, are ultimately guided by and upheld by God. In fact, the strongest philosophical and theological argument in favor of the free market is that it thwarts the attempt of power-seeking men to attempt to imitate God by centralizing the economic planning system through the civil government, thereby directing the lives of other citizens in terms of the goals of some elite central planning board. The free market decentralizes economic power thereby limiting the quest for personal power. It has as one of its most important functions a definite religious purpose: to restrict men in their attempt to play God.
The chance that the natural man professes to believe in does not exist because a sovereign God reigns over all. The free market is free within the all encompassing will of God. To manipulate everyone in a controlled society is to attempt to play God.
