I think it’s worth playing the first because it’s a much smaller scale and sets up the world. This one is set 30 years later so the society from the first game has significantly grown and expanded, with a lot of the evolutions in gameplay stemming from that. You probably could jump right into the second, but you may feel like you’re missing something at the start.
It’s a myth so widely pushed and accepted over the decades that just calling it a myth won’t be accepted as an argument against it at this point.
What I think is interesting is that this sense of fiduciary duty can be used by a company to do whatever they want. Mass layoffs are part of a fiduciary duty to cut costs. Mass hirings are part of a fiduciary duty to expand operations for growth. At this point it’s less a myth and more an excuse for doing whatever.
