Even though I agree that Cindy Avery-Lamb is way over the top, I think the Martins are nothing more than white trash!
They live in a single-family home. Not sure if they own or rent but, either way, there are expenses that go along with a single-family home and making doll kitchens does not bring in a steady stream of money.
My bet is that they live on welfare.
They have 4 children that are not disciplined, have no rules and don't get any schooling. The parents (if one can call them that) are teaching them that they can live off welfare and not be concerned about anything. The father - right on TV - taught them they can lie to others to get their own way.
Simply - White Trash!
