I think this is a big part of it. When I think about how I'd like my work to have a big, positive impact on the world, one of the first things that comes to mind is fixing hiring/job hunting. I'm moderately intelligent and have felt this way for a couple decades, and I still haven't done anything about it because I still don't know how to make it not suck, and I've yet to see anyone else working on a good solution either. I've seen a lot of very smart, capable, and talented people have trouble finding a decent job, and eventually settle for underemployment for a good while. A system that could properly utilize their productivity would be vastly superior to our current system. There's a lot of money on the table for anyone who implements that system. I don't know what that system looks like. I just know with certainty that there's a massive amount of wasted productivity under our current system. What I can tell you is that when I graduated college, the way you found a job was to use Monster.com--a big job search engine--apply to various openings in a tedious process, and interview. Today, you use Indeed.com--a big job search engine--apply to various openings in approximately the same tedious process, and then interview in approximately the same way. There's money on the table for anyone who can improve the system, and no one has. This tells me it's hard. (The fact that I don't know how to improve it a bonus.)
