You're exaggerating the %, in my opinion :) My idea is that only 5% or so will have some actual, organic earning, without boosting their accounts with real money on Steem (which I'm perfectly fine, by the way, wish I could do so as well).
But I have to look at Steemit as a thing for 5, 10 years. Maybe it keeps growing, and maybe our voting power will increase through our hard work, and things will get better. If I had TONS of voting power like a few others do, what would prevent me from helping out good creators? Don't we earn some of it back anyway, isn't it a win/win situation?
Sadly, I'm even more worried with the amount of crazy spam that is hitting Steemit, with posts without any kind of content and people with dozens of accounts voting themselves. It's shady and unfair.
