Well, in market or government, if you have bad people you get bad results. It's not a simple "viable or not viable" - right now we're in a mode where most people implicitly assume that any business allowed to exist is probably OK, and don't really exercise boycott, while relying on regulators etc. to clean up the mess. But that kind of abdication of responsibility isn't a constant of human nature or something, it's just what we've lazily been doing in this society for a while. Likewise, it's not the case where regulators, politicians, judges etc. are universally acting in good faith - it's hard to put a number to it, but there are examples of abuse all over the board as well.
