OP is definitely wrong about rich people not dating middle class people or poor people

A millionaire Heiress isn’t going to date the pizza guy who comes from a working class or middle class family

The millionaire heir isn’t going to date the Starbucks Barista who comes from a working class or middle class family.

Most upper-class elites date other people from upper-class elite families. The only exception might be ‘new rich’ people, like rich athletes, singers, actresses, actors, and models. For example, a man or woman from a very wealthy family might date a rich Hollywood actor who comes from a middle-class family, but they wouldn’t date a ‘regular’ person.

You see this all the time: Nicola Peltz’s dad is a billionaire, and she’s married to David Beckham’s son. David Beckham is worth half a billion dollars. There is no way a millionaire heir or heiress is going to date someone middle class. The idea that ‘star-crossed lovers’ fall in love is just a trope in TV and movies.
