No. Thatās a widely held misconception. Market competition in large, mature industries with declining, or low but stable margins often consolidates around a small number of players as a result of economies of scale and expense capital, until they are disrupted by paradigm shifts and innovation, at which point those large players and industries typically cease to exist. Market competition rarely produces *monopolies* without state intervention.
Monopoly inherently socializes risk, and Capitalism *requires* risk and cost to be fully assumed by private capital.
However, a small number of players in a consolidated market is an effective monopoly if they are working together. Thats why laws and enforcement of laws against things like collusion, price fixing, and other anti-competitive practices are so important. They protect the freedom of the market and allow the invisible hand to do its thing.
