A doctor can't help but work at the world's best hospital, because it probably will still be the world's best hospital next year. A jet engine designer can't help but work at Boeing. A fresh college grad can start a tech business tomorrow.
It is much easier to teach someone how to code than to teach them how to manage. Management is two parts: (1) making sure people produce a good product for a little expenditures as possible, and (2) manage liability from employees. Particularly now, the second part is very difficult to teach.
Most people do not have great judgement when it comes to managing people and it's a really hard skill to teach. You can make someone watch training videos all day that tell them explicitly what NOT to do and they will still do exactly that. Everyone wants to believe they are good at management—very few people actually are. Most fail upwards into it.
