Shorting has to be one of the most mask off financial instruments available. It's literally only available to the ultra wealthy, and the transaction leaves at least one party in a financially worse position, either by forcing the value of an asset lower than it would go at a faster rate, or causing damage to the institution doing the shortselling. The justification is that it forces a correction, but I think it's one of the places where the veil is thinnest and normal people can see what a load of bullshit this all is.
