This is worth a read and seems pertinent to this thread. Its about the deportation of over a million Mexican Americans during the Great Depression in the name of jobs for Americans.

The president who deported 1 million Mexican Americans nearly a century ago
On Feb. 26, 1931, a sunny Sunday in Los Angeles, hundreds gathered for an afternoon of relaxation in La Placita park in the heart of the city’s Mexican community.
Suddenly, a large group of plainclothes officers armed with guns and batons entered the park. Two officers were posted at each entrance to La Placita so that no one could leave. Dozens of flatbed trucks circled the park’s perimeter.
Officers rounded up all the people with darker skin, said Joseph Dunn, a former Democratic state senator from California, who researched this forgotten episode of U.S. history.
Panic swept through the crowd. About 400 park patrons were lined up and asked to show proof of legal entry and citizenship of the United States.
The Mexican immigrants and Mexican Americans who could not produce proper documentation were detained. Then, some were put on the trucks and sent to the city’s main railroad station, Dunn said. Once there, they were ordered onto previously chartered trains and taken deep into Mexico, according to Dunn.
The raid came at the height of the Great Depression and on the heels of President Herbert Hoover’s announcement of a national program of “American jobs for real Americans” — code words for “‘getting rid of Mexicans,’ who weren’t considered ‘real’ Americans,” said Dunn, whose staff spent three years delving into federal, state and local records in the United States and Mexico to document this little-known tragedy of the Latino experience in the United States.
