Reasonable request, Draug. That the system is flawed is not my premise. That is a conclusion drawn if you accept the premise that the distribution of wealth as it exists is bad. I'm not so sure that that's the kind of thing that can be "proven," really. It depends on your metric of success. Let me try my best though... (this is more of a thought exercise than anything else, I'm sure you'll find flaws in it)
A good system would have two goals:
1) stimulate innovation (I'll use that fairly inadequate term as a catchall for "those who create wealth") through rewarding those who do it.
2) providing sufficiently for all contributors.
If you accept that, then a system would be inadequate if either it failed to provide a reasonable lifestyle for everybody who contributed to that system, or if it failed to provide sufficient reward as to stimulate innovation.
That much, I think (probably naively, haha), most people agree with to a great extent, in general terms. So where is the "sweet spot?" Does a sweet spot exist? Most Americans seem to think so (according to the video).
So if you consider on one end the many facts about our society regarding lack of health care, education, housing, and poverty, etc. (I'm only talking about those who work or want to work full time right now, mind you), and if you consider on the other end the massive rewards the system as a rule yields to the innovators, it seems to me that the system is definitely overemphasizing goal #2 at the expense of goal #1.

That's my very oversimplified from the hip answer, anyways.
Do you, Draugnar, think there is a "sweet spot"? Do you think we are exactly on it right now?
