To resolve the imbalance in reawrds allocation being concnetrated int he hands of a few, delegate the power to the whole community that has certain metric met that indicate a real human to filter bots and users who haven't proved themselves yet. Then all votes have a global delegate key applied at the same time in addition to their own keys. Whales can also vote for posts on their own, but possibly with a negative incentive to avoid doing that and promote the power remain int he majority of the userbase. Curation from users goes to users for their SP applied, and then curation for whales go to them. If a globally divided curation pool for whales isn't acceptable, maybe delegate to several communities so that specific curation can go back to specific whales that delegate for those certain communities to curate.
Investors then would not have to do anything. They invest to grow their money. The user base would grow the money for them all equally like a real corporation dividends as well, since it would be a global curation pool for the global delegation key all users use.
Users who invest their time and develop the platform and community will be empowered with intrinsic motivation to be involved, as the voting power isn't concentrated, and this can apply to everything. This will create a decentralized empowered community that will self-direct and self-govern, not be directed by a small pool of power players. This is where things need to head for people to really want to be here. The power imbalance needs to be corrected and this idea allows investors to get what they want, money. Just because someone has more money/wealth/stocks, doesn't give them more power in human relations. To build community people want to run towards, make it empowered this way, Steemit will blow everything away!
