First of all,
Very interesting topic.
I'm glad that you raised the voice about this topic.

By the way,
I want to share some of my ideas & thoughts about this messed up Steem distribution system nowadays.

1. Check how few accounts are holding majority of Steem & SP

1‰(per-mil, not percent) of accounts holding over 80% of whole Steem & SP.
When it comes to ~1%, then app. 94% of whole Steem&SP. (Surprising? I didn't even say how these Steem were distributed at first.. yet)

At this point,
We should accept the reality - Bigger SP makes bigger SP, and Whales has 94% of Steem&SP, simply.

2. 'Delegation' Thingy appeared.. (feat. Bid-bots)

In my assumption, Whales wanted to save their time and collect more coins Easily & efficiently.
Because it would look pretty ugly if Whales upload shit post everyday & upvote each others 10times +@/Day, right?
Then Delegation system appeared.
And Bid-bot system appeared along together.

By these 2 tools, (Delegation & Bid-bot)
1 - Whales can divide their big chunk of SP into several bid-bot accounts, (so they don't have to do ugly things with their original accounts)
2 - Concentrate minnow's SP into their bid-bot accounts for their bigger profit, (poor minnows would think it's win-win strategy when factually it's merely drinking salt water)
3 - Even Sell their vote to minnows for Paid upvoting.
Eg) Some poor minnow who paid 15Steem for 15.0xxSteem might think that it's a good business for him/her, but that is just a hepling bid-bot owner's disguised self voting.

3. Disguised self voting?

Yes. Because by selling vote & receiving same(or more) value of Steem or SBD from minnow - making this scheme looks 'justified' and 'fair' when it's totally Not.

4. Bid-bot is Built-up, Macro program.

Even if someone is going to pay you $10,000 for Shitting on the Street or Public, you can not Shit 24/7.
But Bid-bots Can. This is the difference.

5. So what is the Point?

My point is..
By just 'changing reward ratio for curator' wouldn't be too helpful to fix this serious problem.

Steemit needs Radical Change, not a trick eye.
(You don't use psuedo for cancer, do you?)

-> Kill the bid-bots.

That will be when we can start again.
It's already pretty much 'end-game' phase (since Steem inflation is below 9.5%/year) now, BUT it might giving minnows little more Hope.

Imagine all these whale bid-bots Stop exploiting reward pool!

1 - Finally we will feel some Trickle-down effect,
2 - Can think about Fair distribution by creating & curating quality contents
3 - No more freakin Monkey Post kind of posts spamming all over the trending section. (Newbies feel really hopeless when this happens - Monkey Post getting $$$)

Time is pretty late here and I have to wake up in 3hrs for work.
I wrote this comment just to share my thoughts because it might be helpful to make Steemit change into a better & fair platform for everyone. :)

P.S - I don't mind Whales getting rich.
Just saying that bid-bot is quite tricky & automated Steem&SBD juicer for greedy whales. And it won't be helpful for Steemit platform even in the future.

P.S2 - Dear Planktons, Minnows, Dolphines - Hodl your Steem Hard!! (I am also an Steem Hodler)
HODL will WIN (unless it's EMC2 or Bitconeeeeeeee) ;)

Just my 2 satoshis..✌
