There is no "Sysadmin School" the only way to learn is through experience. The only way you get experience is to do things.
That's why we don't fire people if they make $1,000,000 mistakes, because those are very expensive lessons and that is a large investment in a persons education.
If you only make $1,000,000 mistakes and you keep making the same ones, then it's time to talk safety nets.
We are talking about different things here. You assume the company put you in a position where making $1,000,000 mistakes is reasonable. My point is that companies wont put you in such a position unless you have enough experience that they trust you wont make the mistake. Similarly, for them to put you in a position where you are allowed to make $1,000,000,000 mistakes you need even more experience.
That is why company CEO's have tons of experience if they were hired, they were forced to take the slow path of slowly ramping up the mistakes they were allowed to make. Compare with Bill Gates who was the CEO of a massive global company when he was 30, he ramped up to big mistakes really quickly, no company hires like that.
