The institute of constitutional reform conciliates the principles of democracy and constitutional supremacy and fosters the balance between stability and change. Nowadays, in Spain this change is inescapable. However, in the face of proposals relating, among others, to the distribution of powers between the State and Autonomous Communities, or the recovery of public confidence in democratic institutions, well articulated and sufficiently well-founded, the impulses to contain the perverse effects of globalization on our economic constitutional model, they seem timid and insufficient. Especially as regards the effects of the constitutionalization of the principle of budgetary stability on the social rights. This paper aims to highlight the need to erect walls of constitutional containment to an unbridled neoliberal capitalism, formulating reform proposals to pave the way to the recovery by the State of part of the lost power in the context of the post-Westphalian model crisis.
