I phrased it poorly:

Being an adult child has moral and ethical consequences.

Behaviours and emotions that are totally legit and tolerated in a child are no longer so in an adult.

An adult that has all the privileges and freedoms of adulthood over childhood, like the ability to vote, drink, drive and hold an office, also has to abide by the moral obligations of being an adult.

But if you're rich enough (or poor enough, hah) nobody's gonna hold you to "adult behavior" standards. Is there really a moral or ethical aspect to "don't get into a shouting match on Twitter"? Or is it simply childish?

> But if you're rich enough [..] nobody's gonna hold you to "adult behavior" standards

but that's a problem, isn't it?

That's on us. Why on earth did we stop expecting adult behaviour from ultra-rich people?

Rational and ethical have a lot of overlap.
