I don't think anyone's idea of a perfect future is one where we all still live in a constant battle for enough because, that is where we are now and I don't think many would call it perfection. Balance is required

Perfection even in the future is a facade to attain if we as a people cannot compromise on a balance.

I wonder if for example, everyone went 50/50 on Steem where 50% of personal resources went to self-growth and 50% to community, what would happen

Just like every other good initiative, some peoples greed will not allow them to commit their 50% to the community, except there is a regulation that enforces development of both community and self, then we may never see any profitable result
