It's simpler to just explain it here, rather than dig through my posts and comments to find where I have previously explained it. It's that simple.

Huey Long was a depression era politician, as crooked as any, but cagey too. He proposed that no one should subsist on less than 3% of the median wage, nor be paid more than 300%. This can be trivially done on Steem via code for author rewards.

The current median payout on Steem is about 1500% lower than the average, and this is proof that stake weighting is extracting ~90% of rewards via manipulating the rewards mechanism and getting those tokens into the wallets of whales instead of content creators. That median payout, about .04 SBD today is simply not enough to pay profiteers to manipulate the rewards mechanism(s), not even 3x that value.

It is demonstrably enough to keep some folks posting, because they're posting to get it now.

This simple algorithm forces stake to pursue capital gains, a rising token price, for ROI, and capital gains is the mechanism that has created civilization today, dating back into prehistory as an effective incentive to invest. Eliminating profiteering enables rewards to do what they were intended to do from the initial conception of Steem - encourage content to be created. Enabling creators to attain to the lion's share of rewards massively increases their motivation to do so, and posts on Steem are our marketing department. Folks see those posts and come here to read more. That's how we all got here, after all.

When the market grows, pressure on the price of Steem will increase as more people seek it. This will cause capital gains, and we all will benefit as Steem becomes the valuable money it was intended to be.

That's the idea in a nutshell. I note that Huey Long was assassinated not long after interest in his proposal began gaining popularity during the Great Depression. Thankfully, I am unlikely to suffer more than flaggings on Steem. Hardly even a discouragement, honestly.

Thanks for asking.

Edit: Geez I'm excessively verbose!

tl;dr limiting rewards on posts to no less than 3% nor more than 300% of the median payout eliminates financial incentive to extract rewards using stake weighting. As the profiteering is eliminated, the median will rise towards the average, potentially increasing by 1500%, as well as increasing the price of Steem.

I would add to this eliminating curation rewards completely, to increase the price pressure on Steem.
