Answer with Explanation:
The braceros (under the Bracero Program) were Mexican laborers who were hired in order to fill the gap in USA's agricultural labor. The shortage in labor was mainly due to the World War II. It increased the number of immigrants who wanted to work in the USA. The program promised the braceros that they will be given good working conditions with no discrimination. However, this did not materialize for a long time since many American farmers' income were affected. The program sparked many debates and only lasted for 22 years.
