We had a local company that got raided periodically by the INS. It stopped after someone wrote the paper about how the raids always occurred the day before payday.
The lowlife owner deserves a point for thinking of that, and about negative ten million points for actually tipping off the INS just before payday.
My reason for considering the ripping off of illegals as a reason to be against illegal immigration came from a former coworker. His previous owner had gotten used to just not paying for that last week of the season, and apparently forgot my coworker was a citizen and could do something about it.
Happily, the business owner's mistake ended up costing him a lot more.
