'Perfect competition' is considered both the ideal and the default state in Economics 101. So-called perfectly competitive markets achieve equilibrium when producer supply meets consumer demand.

Economists always say there is a supply and demand equilibrium.

I think competition can make people stronger at whatever it is they're competing on. If we're competing in some athletic event for competitive swimmers, really intensely competing, it's likely that both of us will become better, but it's also quite possible we'll lose sight of what's truly valuable.

Americans mythologize competition and credit it with saving us from socialist bread lines. Actually, capitalism and competition are opposites. Capitalism is premised on the accumulation of capital, but under perfect competition, all profits get competed away.

In the big picture, the whole world at every level, micro, macro, physiological, psychological, material, economical, spiritual, all are a demand-supply problem.

We use competitive markets to arrange for delivery of our food supply.
