Because they are the centre of their universe, they are too big to fail. Failure is always everybody's else fault. The fault is outside, not inside.
As opposed to how we were told: if you are to fail, fail better, fail more, but never in the same way. This is how you learn.
Have you noticed that very few people "learn from other's mistakes" these days? It is like it is no longer a decent way to learn. I believe it is because we are so individualistic and can pick and choose our sources, that we don't regard someone else's mistakes as relevant to our own lives.
I think you only learn if you consider it as your mistake. If you blame some external cause for it, it is not really your fault, right? You were just unlucky. What is to learn from it? And then, how would you really care about how somebody else wins or loses in life if it is all about luck? This is the wrong perception.
