The same ones as today. Even when young adults got jobs here, predominantly Southern California, that wasn’t really where the problems mustered up. It was the youth of Chicano descent not fitting in with the others in schools during adolescence is where I believe things got fuzzy. Gangs were formed, a network, if you will, where these troubled and unfitting youngsters felt at home. Remember, before Mexican immigration, there were mostly Asian farm workers in the late 1880s and early 1900s. By the time 1960s rolled around, the Asian now Americans were running some plantations on the west coast, and if not, they had saved up moneys and their children had opened up their own businesses. So a lot of Chicanos were hired to fill in the void of the Asian Americans having predominantly left the farming system. Of course some of the issues are the same as always. “They will take our jobs!” mentality amongst domestic Americans is the only main one.
