Foreword: I am not the person you replied to, and I also don't agree with killing anybody.

That being said, I have to comment on this:

Killing them is just a waste of talent and experience.

I would argue they have neither. The people they employ are the ones with the talent and experience.

Take Elon Musk, for example. He makes big claims that sound plausible, but anybody who actually understands what he's talking about knows that he's only pretending to be knowledgeable in the subject. It's the engineers and designers at Tesla that do all the hard work in bringing products to market, yet he gets the absurdly high pay package for doing little more than lying to consumers.

I’d go by net worth. And if you’re and $900mm you should be scared that the death squad’s math is different than yours. It’s ridiculously easy to not be a billionaire.

Why kill them? Because they broke the social contract. We let them be enormously wealthy by having a net worth near a billion. It’s not like they were so valuable or productive that they earned that much money. All we ask is they keep their greed under one billion.

If the punishment isn’t severe and final they will find ways to work around it. Their greed cannot be contained by normal methods.

Billionaires don’t add value. That money is locked up. You recommend taxing it at 100% but they will find ways to avoid paying it.
