The 1900–1930 period was the one of largest growth of agriculture in the 20th century until the 1980s. Despite 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."
