Hmmm maybe I'm just weird, but this seems like the biggest non-issue of all the non-issues. Those who "adopted" earliest represented the greatest initial thrust behind the project. Bitcoin was a "silly nothing" when the early adopters got involved... and without them it would've forever remained as such. I sincerely hope those early adopters make a fortune, and I care not at all what "proportion" of Bitcoins any single person owns.
Those who hold the most coins have the greatest incentive to see them succeed, and if they decide to "dump" them, then all the complainers will get a great opportunity to buy for cheap! I really don't see the concern here... but it seems just like jealousy and a misunderstanding of how prices and markets work.
You yourself may not have a problem with it, but it should at least concern you, from the perspective of having more people adopt and use bitcoin.
