There are a number of meatpacking plants in the smaller towns around Grand Island. I bet they would catch a LOT of illegal aliens if they raided them.
Every meat-packing plant in the USA hires mostly illegals, AFAIK. FReepers should chime in if the know of a packing plant that is scrupulous about hiring citizens.
When meat was processed by relatively well-paid union guys who were mostly WW2 vsts, families somehow afforded to eat a lot more meat than they eat now.
