I agree with @captaintj. That concept of wealth redistribution comes straight from communism, and sadly I am experiencing now all the terrible consequences that such ideas can produce.
I think that the beautiful thing about blockchain is not exactly the "redistribution" of the wealth, but the creation of new, free financial dynamics that could make it easier for everyone in our worldwide society to create his own reality, beyond the disgusting obstacles of bureaucrats and bankers.
It's financial freedom! That's a wonderful thing; but freedom is not equality. In fact, they are opposed concepts in this kind of affairs, for when you establish freedom you accept the natural differences among people (those differences brought by their own freedom), and when you establish a forced equality there's no freedom anymore (as it happens in my country).
