I don’t agree that it’s open to interpretation or that your first example constitutes “regular people shit” in any meaningful way. I agree that there’s a difference between having servants and not, obviously, but I don’t think it’s that helpful of a distinction here.
Second of all, flying on a private jet and living in a mega mansion is in no way middle class. I just can’t get on board with the idea of mom picking you up in a Bentley and getting snacks out of a walk-in fridge as being middle class.
I think my point stands. I think it was good to raise them with limits and some humility, that will help them in life, but I think “middle class” and “regular people shit” is simply inapplicable here.
