Le capitalisme entraînerait à terme une concentration des richesses au sein d’une part de la population de plus en plus réduite, et une paupérisation du reste de la population. Un contrôle et une redistribution via l’intervention de l’État serait alors nécessaire. ~Selon Alberto Alesina (dans The future of Europe, Reform or Decline (2006))

nearly all the industries that were highly concentrated in 1997 maintained or increased their concentration and that many industries are now very highly concentrated — HBR

the most efficient player inevitably becomes the most powerful one. Given that people operate substantially out of self-interest, the more efficient a system becomes, the greater the likelihood that efficient players will game it—and when that happens, the goal of efficiency ceases to be the long-term maximization of overall societal value. Instead, efficiency starts to be construed as that which delivers the greatest immediate value to the dominant player. — HBR

The invisible hand of competition steers self-interested people to maximize value for all over the long term only in very dynamic markets in which outcomes really are random. And the process of competition itself works against this as long as it is focused exclusively on short-term efficiency, which, as we have seen, gives some players an advantage that often proves quite durable. As those players gain market share, they also gain market power, which makes it easier for them to gain value for their own interests by extracting rather than creating it. — HBR
