I know! Truthfully I think any society would become more like Mad Max than any other society. At some point, people change. Civilization changes. What's unacceptable today becomes normal tomorrow.

I don't mind the Mad Max overtones myself.

While society might develop into a Mad Max type eventually, I don't think it would happen so soon. I'm hoping there is some good explanation as to where and why this Junkyard group developed. Of all the groups in the show, I can't see a plausible origin for this one.
