 To this criticism defenders of markets can reply by questioning the value of equality of outcomes. What is more difficult for them to reject – because their own arguments often emphasize rights and liberties – is the charge that the inequalities created by unregulated markets can go so far as to seriously limit the possibility of making use of one’s rights and liberties (see also Rawls 1971, sect. 32). In a society in which most goods and services are distributed through markets, those who do not have the means for purchasing them can be said to be free only in a very restricted sense. Even relative (in contrast to absolute) poverty can lead to various forms of social exclusion. A lot here depends on how one understands the notions of freedom and coercion, but in some situations it is plausible that a lack of resources subjects individuals to coercion, not least because it is the enforcement of other persons’ property rights that hinders their access to resources (Cohen 1995, Otsuka 2003, Waldron 1993, Widerquist 2013). As Satz (2010, esp. ch. 4) argues, the vulnerability of agents whose choice is limited by their dire situation, as well as the “weak agency” of individuals who are poorly informed and depend on other people’s decision, can therefore be reasons for limiting free markets. In the 19th century, the asymmetry in bargaining power between workers and capitalist was at the heart of the debate, and it still plays an important role in many countries. In addition, individuals with low human capital, with psychological afflictions, or with a problematic legal status (e.g., illegal migrants) are especially vulnerable in markets. The idea of markets as mechanisms of social coordination is based on a picture of all individuals as sovereign, fully informed, and fully rational choosers. Wherever this is not the case, markets can lead to the exploitation of vulnerable individuals by others. These arguments do not necessarily imply a complete rejection of markets, but they raise questions about the wider institutional framework in which they are embedded. Possible remedies to these problems can either aim at regulating markets or at complementing them by institutions that put individuals on a more equal footing when they enter into exchange relationships (cf. 4.2  below).[5]
