Were you beaten as a child? Exploited for labor, derided for showing emotions? What lessons do you think that kind of suffering teaches? Do you think suffering builds character?
You say you are "willing to take the pain." Then immediately admit you won't feel as much pain as your 'lessers' but it's okay because it'll teach them. Those 'unlucky others' are people who will die. Do you hate your neighbors so much you will let them die after they've been lied to and gaslit by the owning class for decades?
Hurt people have two options; keep hurting those around them, or do their best to advocate, educate, and protect their community from further harm.
Which do you think works better in the long run?
My dude can we not gatekeep homelessness‽ Lack of a home in societies with abundance is a systemic issue stemming from the diversion of tax funds away from supporting those who desperately need it.

Dehumanization of any population is the issue. Your neighbor is not a subhuman to you, nor you to him (I hope) but suddenly the neighbor a few blocks down is a subhuman? What's the local "radius of exclusion" before we start othering more humans?
