"So we take power away from those who 'wield the power', and come up with a better means."
I'm talking about "those who wield the power" in whatever system you come up with. Throughout human history, it's always been one person or a small group of people who wield power over everyone else and that power is always abused. Forcing people into collectivism fails because it destroys the incentive for any one individual to produce wealth. That's why you don't see people living and working in communes.
"The other thing we need to fix is the system of government..."
Isn't that essentially the same thing as finding a different means of deciding who wields the power?
There was an economist named Henry George who proposed that government should levy taxes on land, precisely because it is a shared and limited resource. i.e. we should all benefit from the un-earned value of that resource. He makes some good arguments and it might be a very good system of incentives. It still doesn't address the problem of corruption and abuse by those who wield the power to collect & distribute the taxes.
