RE: If Steem were a country, it would be the most unequal society in the world

You can address this inequality by a combination of several initiatives:
1.) Create a reward pool

2.) Daily ceiling limit to rewards
Setting a maximum limit to daily rewards per Steemian, reduces abuse of the daily rewards pool by way of unlimited postings. Whatever this limit is, it should be carefully calculated and should consider critical factors such as total mined Steem tokens per day, Steemian population, etc. and should also be reviewed and revised regularly.

3.) Distribute Authorship and Curation Rewards using a progressive system
A progressive system takes a larger percentage of rewards from high-income fishes than from low-income based on the concept of ability to earn. A progressive system might, for example, gives minnows and red fishes 90% authorship and 10% curation rewards, dolphins 80% and 20% and whales 70% and 30% rewards allocation.

Another way of progressive rewards distribution could be based on the rewards value. A post that garnered a reward over $1,000 for example should be distributed using a 70% authorship and 30% curation ratio, >$500 using 80% and 20% and >$250 using 90% and 10%.

4.) Daily Limit to number of posts per Steemian category
This is my least favorite solution but I see some merits to it hence I’ve included it here. The thought process behind this proposal is that as you grow from being a minnow to a whale, you’ve gotten better and better hence the quality of your posts should be much higher and more impactful to the community. The opposite is true for new Steemians since you’re just learning the knots and bolts of the ecosystem.

It follows then that minnows and red fishes should be given a higher number of allowable daily posts vs a dolphin or a whale. A max of 15 posts per day for Red Fish and Minnows, 10 for Dolphin, 6 for Orca and 3 for Whales could be a good start.
