Wow, that's .. incredible hubris. There are good programmers and there are bad programmers. There are good managers and there are bad managers. The good variants of either are very valuable and can deliver huge value to very diverse businesses. The bad ones, not so much. Since the computer-based automation of everything is a reasonably recent phenonomen, there have been more low-hanging fruit to be picked by bad programmers. Management is a much more mature field, so having "Teach yourself Management in 24 hours"-level competence is much less likely to have a positive yield. What you're describing is just general intelligence and analytical thought. It's harder and rarer than most people think, and both managers and programmers to be really good at their jobs. But just as there are less demanding management positions in the world, there is an emergent class of programmers who are perfectly capable of building and maintaining simple CRUD apps to spec, but wouldn't need to know half of what is in this guide to be effective.
