A lot of that is simply busy work and can in turn be automated. A huge bank like Goldman is essentially a middleman - and middlemen can also be trimmed down. For example, I was just talking to a friend who works at Goldman as a trader. 75% of his job is to answer the phone and deal with clients issues (eg “why is my account frozen?”). His job honestly sounded like a customer service job. He’s also the person who signs off on wire transfers, something that could easily be automated.

So much of the “value” Goldman supposedly creates is due to them creating an artificial need for it.
