Actually, there is a system for fixing this... and none of those in the power position to exercise it are doing so (likely because he's a sock puppet account of one of them... or they have sock puppet accounts scattered around doing the exact same thing).
It's very simple... there just needs to be an update to the code that limits how much power one vote (as a percent of the reward pool) can have, ever. Put a cap on it. It's actually somewhat unreasonable that one whale vote, no matter how much is invested/saved, can ever be thousands of dollars... unless maybe that was the intent of the engineers who built it the whole time... as a wealth generation tool more than a content platform.
Think about it.... they make it (with this glaringly exploitable feature) and hype up how it's all open, self policed, and votes are all about "curation" and encouraging good content... then, once STEEM/SBD gets a nice fat value, they can use everyone having bought into that to REALLY cash in for all of their work building it and hyping it.
It's literally built into the system... lol. Hell, the self-vote checkbox is checked by DEFAULT even... lol.
