I think you're touching on a serious point that no one wants to clarify properly. Investors in steem should not be entitled to anything but the steem they purchased. In the event it goes up in value, they win.

At the moment, though, they get to endlessly drain the rewards pool for themselves which makes no sense.

It is the witnesses who deserve compensation as they are essentially keeping the blockchain running.

I hope you'll consider joining the conversation in the comments of my newest post on these issues. We really need to highlight these problems for anything to change.
