The current system improperly incentivizes greed. Greed is like gravity, it's simply part of the environment we are in. We can either create mechanisms that benefit the community from greed, like a waterwheel profits from water flowing downhill, or we fail, as these current proposals will do. It is the stakeholders - not the community of content creators - that will profit more from these proposals and gain an even larger portion of the rewards content creators make possible.
Tweaking the extant broken financial incentives is akin to trying to spend less on pumping water uphill. It's not ever going to be profitable to do that, and we need to make development of Steem more profitable than extracting rewards by corrupting curation.
