Between 1931 and 1934, over three hundred thousand Mexican Americans were coerced, threatened, or forced to leave the United States for Mexico—an estimated one-third of the national Mexican American population. Let’s pause to let that sink in: one-third of Mexican Americans were driven from the country against their will because white men, unable to fix the mess they had made of the economy, decided to take their frustration out on brown workers in a fit of xenophobia. Sixty percent of those repatriated were American-born. 16 — Mediocre, pg 144
