Right and wrong are just words. What matters is what you do.

(I just watched that episode of Futurama where Bender was God and it's a perfectly fitting analogy here, I think).

Firstly, your proposal requires a perfect and noble system. There's two major problems right there...one in developing a perfect system, and the other in defining what "noble" actually means.

What's good for one may be bad for another. In often cases it is, especially under a capitalist system where we are made to compete directly with each other.

An example...my box of Kellog's Raisin Bran says, on the back, "Cereal makes eating well easy". I misread it at first and thought it said "cereal makers eating well", and pondered about that for a moment.

As a consumer, we don't want cereal makers eating well. I mean, we say we do, but our actions prove otherwise. Consumers are disincentivised from the cereal makers (as in the grain farmers) eating well, because that means a more expensive product, which is money out of their pockets, which now means they are eating less well than they would have. We are subconsciously at war with our peers.
