This industry has literally killed people before and nothing has changed

Yes, but we are living in the time of, while I hate the phrase, "cancel culture".

While this is usually a pejorative term, I actually take it to mean that whenever an injustice is done, modern social media and the 24 hour news media cycle (and hyper-focused by COVID), has effectively brought attention to injustices/abuses throughout all parts of the American system. This started with the MeToo movement, had its "peak" when racist acts by "Karens" were caught on video and circulated in 2020 and now were are at the stage where a cry for help by 13 employees in a relatively niche environment has broken through into the mainstream. 

This is what's different from years past, so I am optimistic that things will change. That being said Investment Banking is obviously very rigid structurally so we may have to wait a bit for changes to percolate.
