it’s got to do with presumed entitlement ( altering one’s identity’s frame-of-“rightful”-reference ), then with prejudice:

IF I have privilege that those homeless-scum/underclass lives don’t,

AND my privilege is inherent, or earned, or bestowed-by-G-D,

THEN their inferiority is inherent, or earned, or put-on-them-by-god.

ergo, prejudice’s justification, & only through protecting-itself can prejudice gain greater significance…

( I’m saying this as a guy whose 1st homeless experience was in about 1983, & I’ve earned 7+y of outright homelessness )

it’s definitely identity-rooted, & it’s definitely segregation-of-validity-to-the-privileged unconscious-mind mechanism.

As others have pointed-out, through the ages, prejudice is often attacking others out of fear for one’s own weak/flawed “validity”…

so, attacking the “nonvalid” in order to protect the “validity” of the "superiors…

I don’t think any mechanism more-involved than that is required, to understand it being normal all 'round the world…
