They have a share in Steemit. A share that increases by putting in work (either creating content or curating). And yes, they should. That's the whole point of the platform. That's also why SP can't be withdrawn immediately; it's an investment into the platform.

I often talk about community being an important part of Steemit, but the beauty of Steemit is that everyone is a curator. There is no board that nominates curators. There's no process one can game short of actually investing money into the platform, which enriches all of us because it raises the value of the token this entire thing is built on. Curators are already back by the community; groups like Hive account@minnowsupport and Hive account@curie are community-driven curation trails. Hive account@dragonslayer109, Hive account@rhondak and everyone at the Fiction Workshop, and hundreds of other groups of individuals all work tirelessly to find good content and promote it.

You're trying to address a problem that doesn't actually exist. The only thing I've gained from your post is that you don't like whales having as much of a say in which content gets a massive payout, despite their enormous investment into the platform which gave them their position. I understand that, but this isn't a problem. Egalitarianism always ends in a race to the bottom, particularly if it's top-down like this would have to be.
