of this conditions in for rural workers remained harsh with Tancredo Pinochet denouncing the poor conditions of workers in the hacienda of president Juan Luis Sanfuentes during his presidency (1915–1920). Within a dual sector economic model the Chilean hacienda has been characterized as a prime example of a primitive and rural component. McBride, a British who visited Chile in the 1930s, is reported to have been "astounded" to see haciendas with "agricultural methods that reminds of ancient Egypt, Greece or Palestine." The Faculty of Economical Science of the University of Chile was established in 1937 coinciding with the spread of Keynesian economics. Internal growth era Partial industrialization (1938–1958) Industrialization became a state policy from 1938 onwards. This policy line became possible after the victory of the Popular Front, a coalition including communists and socialists, in the 1938 elections. The perceived success of the Soviet economy, the fast growth of other centralized European economies and the influence of Keynesian economics helped to establish "development inwards" ideas in Chile paving the way for active state involvement in the nation's economy. These tendencies were reinforced in 1948 with the establishment of ECLAC (CEPAL in Spanish) in Santiago and the arrival of Raúl Prebisch in 1950 as director of it. Chile's "development inwards" policies were part of a regional phenomenon with Argentina, Brazil and Uruguay applying similar policies. In the aftermath of the disastrous 1939 Chillán earthquake, the government created CORFO (Spanish acronym for Production Development Corporation) to help in the reconstruction of the country and to industrialize the country, mechanize the agriculture and help mining to develop. To finance CORFO loans were taken by the government, the bulk of the taxes were raised and copper mining in particular got an additional tax. One of the early tasks of CORFO was to "solve the old problem of the ironworks". In doing so it injected capital and granted loans to the Compañía Electro-Siderúrgica e Industrial de Valdivia, the inheritor to the failed Altos Hornos y Acerías de Corral. In 1947 CORFO begun the construction of a large steel mill in Huachipato near Concepción which in 1950 begun operating as Compañía de Acero del Pacífico. Another division of CORFO engaged in oil exploration making a breakthrough discovery in northern Tierra del Fuego in 1945. Extraction began in 1949 and in 1950 the state created ENAP (National Petroleum Company) to deal with oil extraction and prospection. Until
