I believe so. The distribution of wealth across a group is not so much a problem as it is indicative of the underlying power structure within that group. Bitcoin takes some power from banks and gives it to individuals in a way which I perceive to be, on net, a boon to humanity. Banksters would only have power in Bitcoin proportional to their ability to trick others into giving them power and money, i.e. they could be nothing more than scammers. Perhaps some measure of "wealth-gap" will decrease, perhaps it will increase, but either way, I believe it will be a change for the better.
