I worked as a contractor for MacMillan (they publish nature) and it's hard to believe how much money they spend for no results. The project I was on had been running for a year when I joined. I noped out after three months and I heard it was shut down a few months after I left with nothing to show.

That was 4-6 people full time and my entire floor of 80 people was full of projects like that - projects you never heard of.

The weird thing is that everyone I worked with directly was very smart, and went on to do cool stuff.

Summary: If I had to guess the remaining profit is wasted on silly projects and high manager salaries.
