Actually it is both. If there were no posts with a lot of votes, and every post got just one minnow vote, then every post would indeed receive a reward, I believe somewhere in the neighborhood of $3 currently (rough estimate). However, this is completely unrealistic.

she was actually quoting me, from a reply to a post about using some baseline amount of guaranteed votes for every post to create a universal basic income on steemit.

My point was that, because of quadratic weighting, if you added X steem power in votes to every single post, it would increase payout disparity, because that X steem power would give more vshares (and therefore more money) to high paid posts. That is to say that you would be giving X vshares to every low paying post, but you would be raising the threshold for how many Vshares it takes to get paid by some number greater than X.

Im not saying that there is any good way to distribute out money to every single post on steemit (or even that it is desirable) but if that is what youre trying to do, for a fixed amount of voting power, the most effective strategy is to downvote many high paying posts, rather than upvote many non-paying posts.
