I expect a lot of Redditors will be very disappointed when they realize just how much money hedge funds made, on average, out of this episode. The WSB moderators really did everyone a disservice by letting obvious misinformation flood the subreddit. It’s hard to view the later stages of the GameStop phenomenon as anything other than a Reddit-fueled pump and dump scheme.
Many other scams (or, for example, theft and robbery) destroy value (as, for example, a stolen wallet is a much bigger loss to the owner than it is a gain for the thief). Or, say, the 2008 GFC made a few people extremely rich (unscrupulous mortgage peddlers, investment bankers creating "complex, highly leveraged, exotic trades [...] without necessarily understanding all of the implications of those monstrosities", etc.), while wreaking havoc orders of magnitude greater on the entire world.
