I don't... I don't think this guy understands how some basic mechanics work.

Still, if the metaphorical gears were degraded by warping instead of grinding down the teeth, the machine would still work, but it would grind and warp other gears. Also, if he was assuming a redundant system (multiple gears doing the same job in case of failure), one gear degrading would put more work on the ones that remained.
In any case, the definitions are not his own, but were taken from older works. They're accepted definitions for dysfunctional family makeups, and the roles people play in them.

My case was an addict Mom and absentee Dad. When taking care of my sibs and I on her own, she was responsible and driven, but she kept looking for partners who were Enablers whenever she could, and once she did became a victim and stopped trying. I love her, but as long as her self-victimization is being Enabled, she isn't going to improve her life.
