Bitcoins seem to get pretty well dispersed now, due to the difficulty of creating them and the number of people involved. Creation of new coins should have followed a logistic curve instead of log. Or maybe even in proportion to the number of transactions. That might have been more stable. The whole bitcoin economy is hostage to early adopters periodically removing vast amounts of other people's wealth basically for doing nothing at all.
Still, what's done is done. Not much can be done about it now. But it's something to consider if and when a new currency is designed.
At the time, nobody knew what a crypto-currency was (except for the lucky few who happened to be interested in the subject.) Given that Bitcoin is likely to fail at some point in time in the future (even if we're counting beyond our own lives), by then, if most people know what Bitcoin is/was, and Bitcoin 2 released its genesis block, there would be a much larger number of people lining up to take a slice. Then it would be much more balanced, and much more spread out. But you gotta start somewhere, and someone's gotta do the mining to keep the whole thing afloat.
