Should Billionaires Exist?

No disagreement, just different focus. Personally, I wish not to grant the state any meaningful power to impose wealth accumulation restrictions. That will only lead to other restrictions in some government-led scheme of "social justice."...
I agree, the more control we give any governing body over us, the more power we will lose to self regulate as a society.
And yes, that's fantasy land, but it's something to aim for, or to navigate towards.
And yeah, unfortunately we can't live in an ideal society because there are some people out there who want nothing more than to cause chaos.
