Hello @vegeta You pretty much right on you points.
Crudely:
Curators (Up-voters) get a share in the rewards. If you have more voting power, you get a bigger share in the rewards. Voting power is inextricably linked to the amount of Steem Power you hold.
"If you have more voting power, you get a bigger share in the rewards." Which means that the rewards will concentrate towards the whales. The distribution of wealth needs to be spreaded out better if Steem wants to hit critical mass.
