The cool thing is that cheat detection/unfairness detection seems to happen at the semantic level of reasoning. You can see this with kids - one example I recall is a friend's 5 year old being upset at seeing another kid with ice cream. $Parent said it was that kid's birthday (who knows), and her kid immediately got over it.

So if only billionaires were human, we could just suggest their semantic categories were wrong. <rimshot>

Maybe something about a previous life?

I'm fairly sure "it's their birthday, so they get a tax break" won't work.

Are we sure? Maybe no one has tried yet...
