Problem is these same migrants also take carpenter and factory jobs. I picked apples in upsate NY mid 70's not a single latino in sight, all black. I was the only white kid. Worked the citrus packing houses in Florida, no latinos, all black and white. Worked dairiy in Ca, mostly Portugese. There was Mexicans in the peach orchards in Ca., but they moved from location to location. They lived in the shadows and their families remained in Mexico.
Point being we did well before and if forced to work to live we can do it again.
