Are unions universally good? No, because humans are in the loop, and humans can do bad things.

Does that change the fact that the concept of a union is one of the greatest innovations in all of human history? No.

Can unions today help disparate human workers collectively improve their working conditions? Yes, because this is what unions were designed for, and I think is the key outcome the Rockstar folks are betting on.

For a recent example, read up on the Samsung union bargaining for company wide bonuses in the wake of the huge profits made off the surge in demand for memory.
