I think its a balance. People who invest large sums of money into the system have a right to earn a good return on their money. If they don't earn it here, they will take it elsewhere and the Steem price is all about supply and demand at the end of the day.
Content creators need to be rewarded appropriately too or else they leave and their content goes with them.
The deck is probably stacked to much in the favour of money at this stage, but how to come up with a better system is the problem. They changed the author/curation reward pool split last year and the amount of curation plunged. So even when attempts are made to solve problems it can have unintended consequences.
