To answer your question, economics is like entropy. Money (value) will always actively seek to consolidate given enough time. Give a room full of people an equal amount of cash and days later 90% of money will be owned by a 1%.

Unless whaleshares can come up with a totally different tokenomics, give enough years can you'll end up with a top 10 accounts owning 90% of the coins.

I don't deny that Steem started out bad though. Those who knew of Steem early (and took the risk and expense to mine it) are now the large stakeholders you see around. I kinda just live with it now i guess.
