1988 Chilean constitution

As part of the “managed” transition to democracy in Chile in the late 1980s, the Pinochet dictatorship rammed through a new constitution to ensure that their neoliberal extremism could not be reversed by a later government. From this Jacobin article(external link):

A neoliberal economy is practically baked into Chile’s Constitution. Enshrined in it are “right to work” labor laws, the “choice” of private health care, and the prohibition of strikes by “state or municipal functionaries” and workers at public utilities or firms at which “stoppage would seriously endanger the health, the economy of the country, the supply of the population or national security.” The constitution outlines expansive private-property rights and protections from government expropriation.

Critics of the constitution argue that it privileges elites and makes it difficult to effect structural reform. Changes to the electoral system, including “healthcare, water rights, pensions or the power of the Constitutional Court, require up to a two-thirds approval by Con­gress.” The voting system has also historically privileged the two largest vote-getters in congressional and senate districts, creating a near two-party system of an elite center-right and an elite center-left coalition.
