A company is like a chain, as strong as its weakest link. There is not much gain to have some links much stronger than the others.
The famous "I've learnt my lesson" which means you really reached the same low level of incompetence as everyone but secretly thinking you are more competent than all the others.
The funny thing is that among all those incompetent peoples / idiots mentionned there are probably smart people who just learnt their lesson years/months and adjusted to the weakest links in the chain.
