@haejin can't fix the problem. He can take advantage of it, just like the other whales do, and he is.
I reckon this is the strongest incentive to fix the problem, because it's a direct attack on the ROI of whales--which is the source of the problem.
They can fix the problem, but only if they relinquish they're vampiric feeding off the rewards pool, and act as actual investors, by encouraging capital gains--which will make them far more money than mining rewards ever can.
