Why would you assume forming a fair economic system would be easy and simple? Is a fair justice system easy and simple? Do you want to destroy the justice system and replace it with "king decides" like we used to have because it's oh, just too complicated to have a legal system?

>No, we're still there

You're still here. You're still asking the question "what's the exact volume of blood a human body is supposed to have? Answer me that!" while I'm asking "how can we better identify and kill mosquitoes?"

It's worth noting that in nature, parasites often try to "trick" hosts into believing that an exchange is necessary or mutually beneficial. That can make killing parasites complicated. Nature doesn't give up though. Hosts will form elaborate defenses to protect themselves.

>You haven't even established what a "parasite" is

I gave a very clear definition above. If you take a greater than equal share of the world's wealth then you are a parasite on somebody else's share. This includes Saudi Princes who contribute nothing and sell access to oil from under "their" sand. If you extract the value of somebody's labor you are a parasite. This includes Alice Walton. This includes every businessman who exploits his workers. This includes shareholders of those businesses.

Some parasitic wealth transfers are more obvious than others. Some are legal. Some are not. Some are subtle. Some are not. A person's wealth can constitute a mix of parasitic wealth transfers and earned wealth. A parasite can also be a host. Sometimes these transfers can cancel each other out.

One thing that is always true is that the more parasitic a wealth transfer is, the more absurdly insistent the parasite is that they've really earned it. Hence all those stupid fawning Forbes articles about how they work long hours and sleep under their desk. That is the parasite trying to trick the host.

It's worth remembering that the justice system is not perfect. Perfect justice is impossible. Mediocre justice is hard. Good justice is very complicated. So the logical corollary of your argument that "perfection is impossible, why bother trying" is that we should trash the entire justice system and return to something nice and simple like "king decides". Is that what you want though?

>See, we're back to asking what amount level of "wealth inequality" is OK again.

You certainly seem really keen to keep dragging the question back to "what is the exact volume of blood a mosquito victim is supposed to have, anyway, huh?"

If mosquitoes could speak, I'm sure it'd be something a mosquito would say :)
