In 1964 he completed Merchants of Labor, where he moved to LA to worked for one year as an Economic and Opportunity Agency officer. This was another way he helped the Latino Community and the Chicano movement because it showed his focus and organizing efforts on the Mexican urban working-class population for the remainder of his life.
Not only was Galarza an activist leader but he also became an author, he wrote many books about the farm labor. He authored Spiders in the House and Workers in the Field (1970), Barrio Boy (1971), Mexican Americans in the Southwest (1969), and Farmworkers and Agribusiness (1977), all these books have a different meaning behind it. For example "Barrio Boy" is mainly about his life and how he felt from transitioning from one country to another. Galarza mentions two reasons why he wrote this book and he mention how there's a " historical and one psychological". The historical reason is that he acknowledges the importance of his experience historically, since many families have migrated from small Mexican villages and landed in the United States. The psychological side is the author's desire to communicate his confidence in his self-image as a Mexican immigrant..
Mr. Ernesto Galarza, died in 1984 but all his hard work and sacrifice that he put in so that the farm workers would have 'equal rights' still continues to this day. He inspire many to continue the strikes and the boycotts like, Cesar Chavez who was another farm labor activist that also fought for appropriate wages and working conditions for the farm workers. Galarza changed the perspective of many regarding the farm workers because he went through the discrimination himself when he had first settled in California and this is what made other realize and consider their rights.
