I actually think it's a net negative, in the current US. Now there are good things that capitalism and markets do, but the way it's currently functioning no longer provides those benefits, because algorithmic trading has driven the signal to noise ratio in to bedrock. Wall St at this point is basically just a social noise amplifier stuck in an ugly feedback dynamic with the rest of the country. We long ago stopped hearing music from the underlying economy, we're on to mic static screaming at full volume. If I could wave my magic wand, Id switch to a single exchange which resolves all outstanding bids/orders once every 10 seconds in a single transaction. (You could create a single virtual exchange out of many actual ones using smart contracts.) I just don't believe Wall St would stop generating any real value by being forced to slow down and take a breath (and allow humans to act on relevant time scales). Instead, we have a noise amplification arms race.
