Your wording makes it sound a bit like you think decentralized means distributed wealth? There are still going to be obscenely rich bitcoin holders and very poor bitcoin holders.
I don't expect Bitcoin to repeal Pareto's principle.
http://en.wikipedia.org/wiki/Pareto_principleIf everyone tries to produce the best they can. I expect 80% to go to the top 20%. This is actually fractal and so the top 4% get 64% of income. This is natural and fair to me.
But Politicians and other Tax Parasites might have to find honest gainful employment instead of riding along with their feet up and not peddling.
