It's a self-correcting problem over time though...

Some ways it might change:
New money comes in and the current stakeholders are just built into the economy.
The price falls and new people buy in and change the culture or the price comes down enough average users can and will buy stake.
People understand that the Steem is the blockchain token and they build Platforms and SMTs for purist content sites and interaction.

The distribution is getting better and that should help spread steem around to more hands, with more visions.
