While I don't disagree with downvoting as a whole, I personally think that downvoting 'because it has to much reward' should actually just stop. I think part of the problem is sometimes people tend to compare the pending payout and perceived effort in making a post to real world jobs and income.
Nothing should be 'overvalued' on hive as a post unless it's like... really blatantly low effort i.e single picture memes etc getting $100s of dollar rewards.
The only other thing to do is call out those who do just downvote because 'it pays to much imo' If they are witnesses then vote against them, if they have proposals unvote them of you voted them, don't give them support and like others have said find witnesses you can support. even if it feels like your stake isn't enough to make a difference it actually does and there are bound to be many more who feel the same way as you.
I personally haven't downvoted to 'adjust reward' because I think it's stupid to do so. I mean.. it might even be stupid to do so on single picture memes cause I mean.. some of them can be really funny and totally change the mood of someones day and they may thing hey thats worth $10000 right there!
In the end, people's understanding of something value is subjective and highly opinionated and I don't think we'll be able to change much about that.
EDIT: I'd also like to add that better token distribution would also greatly reduce the likelhood of this happening. Right now we have very high staked accounts. If hive some proper mainstream like facebook with million if not billions of users the token distribution would be SO thin that a downvote/upvote from any single account would at most be work a few cents. Assuming the price of hive doesn't got completely nuts.
