I think a big part of the problem is that even though Steem has DPOS, there is no community agreement when you join. So we have no rules, and we have no way to make decisions as a community about changing the rules. Right now the dev team has complete control over the content and curation rewards algorithms. There needs to be a way that people can propose changes, get the proposal seconded, and eventually have a community referendum on whether to apply the rule changes.
