Like, asbestos miners losing their jobs was a necessary result of shutting down the asbestos industry. It's not that it's fair, but it's not a reason to keep mining asbestos. Obviously ideally Wells Fargo could be reformed somehow, but the "corporate death penalty"[0] exists for a reason!
But it does send a message to the broader industry. Sometimes a few rouge cancer cells can kill the entire host. And this is the second time around for them.
