> Most professionals have to do the task that brings the most value if they want to make a living.
The comment was "worry about bringing the most value to society". And you think that's what pretty much anyone does? Finance, ad-tech, real-estate flippers, and numerous others may not even add any value. Others are all about internalizing profit and externalizing costs. At the very least, "bringing value so society" is a tertiary goal for most people.
I choose a few people who could be making more doing something else. I'm sure, some people who work at nonprofits could also make more in a different field. But those are the only people I've seen worry about bringing value to society.
