The objective of this essay is to contribute briefly to the understanding of the conception of the Mexican State from the perspective of economic policy, under the premise of the struggle between two ideological currents: 1) the one that promotes the intervention of the State in the economy and in the market and 2) the liberal one, which, as a political strategy, it changed its name to neoliberalism in 1938, and whose purpose lies in the liberation of markets and the restriction of the role of the State in public affairs. In this sense, this text also addresses some relations between Mexico and the United States, as well as global events as important factors in the construction of the national state. The essay is presented in three sections: 1) Welfare State: the development of its conception from the conflict. 2) Neoliberalism and the deconstruction of the State and 3) New perspectives on a global State. In addition to an introduction that puts into perspective the problem of the formation of the State since the Independence of Mexico.
