Back in the 1850s a big argument slave owners used to use was they couldn't afford to employ free blacks or whites on the plantations, because the wages would put them out of business. How many times have we heard that same argument used to justify the current broken immigration system? We had a civil war that proved how bogus that argument was.
Oh yes all those businesses would just fold up if they couldn’t hire illegals. Problem with that argument is when the government actually does a big workplace raid and detains all the illegals then citizens line up for their jobs.
