no offense to you personally, but that's a naive position. "greed is good" is a movie platitude, not the basis of our complex socioeconomic system, so it's practically useless to argue against it. more crucially, your solution says nothing about the universality of human desire, which is why it's simply a non-starter.

if you really want to improve social equity, distributing esteem more widely[0] will be more fruitful as a guiding light than trying to devise a more perfect, automation-based socialist/communist economic model. extreme automation will inevitably increase inequality as capital will find ways to corner ownership of the machines and hoard the productivity gains, no matter your good intent.

[0]: 'flatten the pile', if you will.
