Saul Bellow says

The country is proud of its dead poets. It takes terrific satisfaction in the poets’ testimony that the USA is too tough, too big, too much, too rugged, that American reality is overpowering. And to be a poet is a school thing, a skirt thing, a church thing. The weakness of the spiritual powers is proved in the childishness, madness, drunkenness, and despair of these martyrs. Orpheus moved stones and trees. But a poet can’t perform a hysterectomy or send a vehicle out of the solar system. Miracle and power no longer belong to him. So poets are loved, but loved because they just can’t make it here.They exist to light up the enormity of the awful tangle and justify the cynicism of those who say, "If I were not such a corrupt, unfeeling bastard, creep, thief, and vulture, I couldn't get through this either. Look at these good and tender and soft men, the best of us. They succumbed, poor loonies."
