Maybe the majority of people in the world are scumbags, but we non-scumbags don't interact with them on a regular basis. But since everyone has to go to the DMV from time to time, it makes sense that you're most likely to encounter scumbags there, just by their sheer numbers.

Also, you live in the Southwest. Meth, etc.

That's what it's called here. My girlfriend got a new car and was getting it registered, and I just told her she should go to a third party place, BUT NOOOO. It's like ratchet town every time I go, kids running around everywhere, people wearing Rocawear.
