Answer:
The name of the government initiative that involved contracting over four million Mexican migrant workers to come work in America was the Bracero Program.
Step-by-step explanation:
The Bracero Program was a treaty signed between Mexico and the United States in August 1942 in which Mexican workers were invited to come and work in the United States to fill the lack of labor created there by World War II.
Mexican workers who worked under the Bracero program were called braceros. They mainly did heavy physical work.
About 4.5 million Braceros entered the United States between 1942 and 1964. A large proportion of these did not return to Mexico after the expiry of the temporary contract. As a result of the Immigration Reform Control Act of 1986, illegal residents living and working in the United States were given amnesty or legal status.
The program led to progress in American agriculture and led to its mechanization, but from a humanitarian point of view it is seen as a major failure. Many did not get the rights and payments they were promised, and both governments took few actions to do something about it.
