You must be one of the Real People™ if you make above a certain amount of money or you have certain professions or if your family has a certain amount of money then you are considered a real human. Importantly you must also be male and cisgenderrd and heterosexual, though enough money can counteract these effects.
The reason that most humans are not considered Real People™ is because it’s the only way for folks nearer the top of the pyramid of social hierarchy to justify their existence. Poor folks and people who don’t have professional careers must be less than those at the top and the ones at the top must have special criteria that means every judgement they make must be better.
I used to be on disability and when I went in to see healthcare professionals I was basically treated like dirt and was never believed about anything I said. Then I went to law schools and suddenly everything I said mattered. It’s wild how much differently folks treat you when they think you are Real People™
To be fair most of them were children at the time
