Yeah. No you don't. You're, somehow, a fraction as competent and professional as some teens and 20-somethings making toys in their spare time, if you do. Definitely deserve seven-plus figure salaries for that.
The money is there so that things that are desired happen mostly on time.
You are flipping this around: "companies pretend they need this whole fucking edifice", but they'd need to pick the winners first. those people need no management for them to do what they are motivated to do, but corporation have some people they are asking to do something they might not care much about - the same results aren't guaranteed.
