This is actually incorrect and European nobility showed the template.

Do you know who served in the houses of the truly powerful? The children of the slightly less powerful. For example, the Groom of the Stool, charged with wiping the king's ass amongst other toiletry things, was a position hotly contested by noble families of all levels.

Once they wipe out the poverty class, their servants will be what remains of the middle class, who will be desperate to maintain their lifestyle.

It isn't spoken of out loud but among the ultra wealthy, having an all white staff is considered a mark of social status. And once those disenfranchised middle class families bend the knee, their uncertain future is resolved and we have reinvented feudalism.

It's where we're heading.
