So, this might not be my strongest metaphor, but I see free markets a bit like the arena in fight club. Two people fighting, the others forming a circle that pushes the combatants back to the center. We want the "fight" to occur. Economies are complex systems and humans have extensively proven that they're not good at running those. Free markets are the most effective way to facilitate technological progress and economic growth which indeed benefits everyone - although not in equal amounts. However, we have to be mindful that free markets contain the seed to their own destruction. On the upper end, there's monopolies, price fixing and other anti-competitive behavior that disables the price finding mechanism. On the lower end, there is poverty which prevents people from participating and discourages entrepreneurship. Good regulation does just enough to keep the fighters in the arena.
