The Efficient Market Hypothesis

If the EMH is not true, then someone can beat the market. If someone can beat the market, that someone must be able to beat it and beat it consistently. If someone can consistently beat the market, this implies that human thought is wiser than the invisible hand at resource allocation decisions. Some humans will be better able to allocate resources than the market. Therefore, some amount of human planning will be objectively better than letting the market make every allocation decision.
