I think you are missing the point that this is simply intended to provide insight into what is going on inside the head of the person who is doing the hiring. They might be excruciatingly polite in what they say to you directly and personally, but in their mind they are thinking "Why is this fool wasting my time with this stupidly long resume." He's telling the world in blunt terms the reality of what it takes to get hired and how people are going to see you. He's not composing a personal letter to you.
