People now identify themselves as belonging to a social class by subtle cues, it's like an unconscious messaging system to signal that you belong to some sort of club.
That's what "being raised right" means now.
It's now backwards to check if someone comes from a good or rich, noble family.
Instead, we check other subtle things.
Spend 5 min with anybody, and you can somehow know if that person can belong to your group of friends.
It's like animal checking each other' scents to accept them in a group.
