Traditionally, liberal constitutionalism evolves around questions of normative equality of citizens. Less explored is the question of material inequality as part of the constitutional law discourse. Partly, this might be explained by the fact that liberal constitutionalism rarely engages with the markets – the economic system is often seen as independent from the political system, and even more so from the constitutional regime. As a result, not only the relationship between the constitution and the market, but also the relationship between wealth inequality and the constitution remains little explored. However, newer research has been pointing out that indeed there is not only a connection between (constitutional) law and the economic organization of a nation, but also more specifically between liberal constitutionalism and capitalism. Against the backdrop of Piketty’s research, the question arises: if inequality continues to escalate amidst the functioning of markets in line with neoclassical principles, and if law constitutes markets, what implications does this hold for the stance of liberal constitutional law on material inequality?
