Mighty suspicious if you ask me.
Could it be all those great Tex-Mex cafes one finds in Tejas.

20th century abortions are up over the rest of human history. The meeeeeeeeeeeeeeeeeeeeeeeeeeeee generation.
BTW, there were substantial numbers of Mexicans in (mostly Southern) California, Texas, Arizona and New Mexico, but they fell into two categories: if they were ordinary peasants, they lived an essentially subsistence life not much different than in Mexico. if they were part of the old Spanish/Mexican upper class, they integrated pretty successfully.
In California, for example, the old Spanish/Mexican elite were known as Californios and were often highly respected members of the upper reaches of California society. As a small child in San Francisco, I remember being introduced to one or two of them, very very old women (in their 90s-100s in the early 1950s), as great ladies of California.
