But it's true, of course the big accounts have a huge influence, and of course this is mainly because they were the first ones to be here, but that's how it works unfortunately. And the only way to change it is having the huge crowd of small people powering up more Steem and starting to vote the best witnesses.

There have been multiple posts in the past analyzing this and a huge portion of Steem and Steem Power does not vote for any witness which further centralizes the process.
(This counts for any type of democracy).
