If there is anything good about exile, it is that it teaches one humility. It accelerates one’s drift into isolation, an absolute perspective. Into the condition at which all one is left with is oneself and one’s language, with nobody or nothing in between. Exile brings you overnight where it would normally take a lifetime to go.
Literature sort of makes your daily operation, your daily conduct, the management of your affairs in the society a bit more complex. And it puts what you do in perspective, and people don't like to see themselves or their activities in perspective. They don't feel quite comfortable with that. Nobody wants to acknowledge the insignificance of his life, and that is very often the net result of reading a poem.
