Ordoliberal theory holds that the state must create a proper legal environment for the economy and maintain a healthy level of competition through measures that adhere to market principles. This is the foundation of its legitimacy. The concern is that, if the state does not take active measures to foster competition, firms with monopoly (or oligopoly) power will emerge, which will not only subvert the advantages offered by the market economy, but also possibly undermine good government, since strong economic power can be transformed into political power.
