During World War 2, many Mexican Americans enlisted in the military at higher rates than the overall population to escape poverty and show patriotism. After the war, the GI Bill helped veterans like Guy Louis Gabaldon with education, and urbanization increased as Mexican Americans moved to cities for better jobs, growing the middle class and influencing a breakdown of traditional families and culture. Public policy alternated between programs like the Bracero Program and Operation Wetback that increased legal and illegal immigration, while the generation and intelligentsia also helped shift public perception of Mexican Americans positively.
