The Decree of Necessity and Urgency (DNU) issued by President Javier Milei, titled "Foundations for the Reconstruction of the Argentine Economy," is one of the largest deregulations and modifications in Argentine history and represents an extremely significant measure in the economic and social context of Argentina. The DNU covers a vast spectrum of regulations and reforms, focusing on key aspects, mainly on labor reforms, economic regulations, and energy policy, in the face of an extremely critical economic situation characterized by the risk of hyperinflation and a context of prolonged economic stagnation. Milei's government argues that the policies of previous governments have led the country to a state of emergency, with potentially catastrophic inflation and an extremely high level of poverty making this law necessary. In conclusion, the importance of Milei's DNU lies both in the country's crisis situation and in the number of laws it covers, in the deregulations it seeks to carry out, and the structural, political, and social changes it proposes. We hope this book will be an excellent tool to facilitate the reading and understanding of the changes proposed by Milei, whether you are in favor or against.
