We had and still have a situation where many of the previous witnesses had been witnesses for a long time, collecting 350 steem per day and voting each other in and keeping each other in. As they (witnesses) gained steem each day, they became more and more entrenched in their positions. Getting harder and harder to ever displace them over time. Not to mention many witnesses all voted for each other's posts and SPS proposals as well. Over the past year or two it had very much become a "good ol boys club" where they basically controlled the blockchain. And it was mostly happening due to the votes of a handful of the largest whales as well as all voting each other. It shouldn't work like that.
