You've got some good ideas, there, but nix the social engineering.  For that you need 'enforcers', and things get ugly pretty fast.  For a quick intro to economics, try looking at Youtube, there's interviews with Milton Friedman there.

I suggest you take the opposite route, and look at 'greed as good'.  Everyone that strives for something better - a better job, education, house, etc...is motivated by the self interest that disparagingly may be called greed.  When you create government enforcement against 'greed' you only empower the greed of the enforcers.  The evil that you believe lies with the greedy capitalists in the socialist/communist model, is transferred to evil of government.  Of the two, it's far better to have the greed as a motivating factor in the private business sector.

And you don't want to take away peoples' incentive to improve their lives.  In fact, you don't want to limit it.

The book Atlas Shrugged was not a manual on how to run socialism....
