This is the ultimate Texan dog-that-caught-the-car moment. I remember talking about this in school in Texas 25 years ago when Republicans were complaining about immigration. Several students brought up that the farms are all tended by "seasonal workers," which meant immigrant labor, so what was the Republican answer to that? They didn't have one, of course, not a realistic one. It was the same talking points then as now of "American workers" filling the gap, and even then those jobs didn't pay a living wage, so no American would take them. I bet they pay worse now.
They had 25 years to figure this out, but of course they had no intention of figuring it out.
