I'm remembering this very poorly, but I seem to remember something like, as an example, a hail storm comes through and tears up a lot of roofs. Roofing crews pop up everywhere, and if you drive around and look at them the vast majority look like hispanic/Mexican/whatever term you want me to use that isn't racist. The workers are technically employed by the foreman, who is contracted by a larger company (the one that cashes the check from insurance or home-owner). So it's not actually the roofing company illegally employing these people, but the foreman. Actually I'm just now remembering that's how my buddy's dad runs his crew. Pays them cash I believe.
