From the Dallas Morning News:

The stock market tanked, unemployment rose and cries grew forceful against Mexican immigrants.
It was 1930.

The piece goes on to lament today’s parallels to the Mexican Repatriation Program, which deported illegal aliens (whose children went with them, hence the subsequent hand-wringing about American citizens being made to leave) and prompted significant voluntary attrition of the illegal population. (Even Wikipedia acknowledges that it was part of a broader enforcement campaign by the Labor Department (which had immigration back then), and only 20% of the total number of illegals removed during that period were Mexican. This being the 1930s, there was no doubt a certain nonchalance about constitutional rights (even real rights, that existed before Earl Warren); but, mutatis mutandis, we’re seeing a replay of this, and it works.
