I thought of a few stupid things, but everyone talking about kids made me think of this one.
I am strongly against Trickle down suffering.
"I put up with this terrible thing when I was your age, and even though we could stop it from happening to anyone, it's important that we make YOU suffer through it too."
Hazing, bullying, unfair labor laws, predatory banking and more. It's really just the "socially acceptable" cycle of abuse.
