Well this proposal doesn't aim to fix that really. It's just a way to better distribute the money that's already here. Right now 90% of it goes to the top 100, and the last 10% is trying to be taken by maybe 1,000 more.
All I propose is for that last 10% to be shared among 100,000 more evenly. This in turn would create a site with a far better reputation with less spam and such, and outside investors would read upon it more fondly and throw their money at it.
I can't see this system providing a higher income than vote selling currently does, but if we assume selling 40,000SP for 600 Steem which just happens to be the rate I noted via blocktrades some weeks ago, then their profits, using a total of 4 million steem power, would be 60,000 a month or $720,000 a year - exactly double my random example of $360,000 a year. So my idea wouldn't be extracting money from nowhere - it already exists.
I am awful at maths though so feel free to clarify if I'm getting things confused. Doesn't seem so, though
