“If they can afford such nice cars, then how are they poor enough for Section 8 housing in the first place???”
There are several answers. I had renters buying steaks on EBT and selling them for cash. They were also growing marihuana on my property. When I was at the welfare/unemployment center the clients couldn’t use their cell phones inside. They’d step outside and lean against the mirrored wall-sized window where I was taking a “free” computer class. They’d talk about committing robberies, selling/buying drugs, prostitution, etc. They are making plenty of money. They just don’t report it.
These days they’re called “entrepreneurs”.
