You should get out more.
Illegals have completely taken over the service industry, all major hotels, completely taken over the construction industry, taken over the restaurant food service industry, they drive trucks, they have taken over the warehousing industry, what is left of manufacturing etc. You name it.
When you see a crew of illegals at McDonalds, they aren’t employed by McDonalds, they are employed by the (typically small) franchiser who runs the business.
Oh shazamm! How very convenient for Micky D. Ya think this is some kind of mistake?
You are aware that 75% of McDonalds are franchised, and I doubt this has anything to do with illegals, since that pattern was established in the 60s.
