You have made your decision without even reading his post and I think you have been swayed by others. I could be wrong here and if so please feel free to correct me.
No one asked me to look at this post or express any opinion on it. I was randomly reading the hot or trending page (I forget which now) and I started reading the post due to its title.
I read enough of the article to conclude it was overrewarded nonsense. Of course, that doesn't mean I necessarily disagree with everything said in it. But when it begins with poor reasoning and a lot of hyperbolic content, I think it's quite fair to downvote it, regardless if there was some later truth contained in it that I never got to because of a poor beginning.
Also, as a practical matter, it's been my experience that posts that begin illogically don't tend to get better later. But since you asked me in a reasonable manner, I have taken the time to read the whole post now. And having done, I can't say I've changed my opinion about the post.
From what I can tell, the OP is trying to knock down a strawman argument. I can't be 100% sure who the OP talking about, of course, because he doesn't name any names. But the proponents of "skin in the game" that I know of, most prominently theycallmedan, have never made the argument that the OP is arguing against. They have made the argument that you cite and that I referred to in my initial response to the OP (having skin-in-the game encourages decision making that is beneficial to the system involved).
Nor have I heard anyone else here make the "pro"-skin-in-the-game argument that the OP is railing against. It should indeed be obvious to anyone of reasonable intelligence that having wealth doesn't make you smarter than other people. As an obvious extreme case, babies born into wealth would need to be smarter than adults for this to hold true.
But I haven't seen anyone making this rich=smart argument here. Yet the OP goes on like he's uncovered some major discovery by citing what IMO should be an obvious truth to anyone who has had the chance to meet rich and poor people, and how he claims he has exposed some deep underlying rot in Hive, based on it.
Now, a much more interesting article would be an analysis of why the world is full of rich people of average abilities and what the impacts of that are. I've thought about this issue for a long time and I'll probably share some of my ideas about it, once I get some time.
