<Then, the death penalty. Beats the hell out of me how that got in there.

I was just making a point that a complex system of legal checks and balances seems to work in that case, similar to the current legal regulations on corporations. That both could be improved is certainly worth debating. The unfortunate tendency in business regulation is overkill, and I hope we can avoid that.

Despite your worries about "greed," designing a system that makes it impossible to get rich is not going to result in a country you really want to live in.

No one seems to be looking for ways to exonerate the people already executed. You say there are none. I wonder what the odds of that are?

The anti-death penalty people are certainly looking. If no solid evidence of the execution of an innocent person has surfaced, it isn't because they aren't trying to find it. At some point, I think they will. As you say, in the entire history of the formal death penalty, it does seem unlikely that no innocent person was ever killed.
