If poets were realistic, they wouldn't be poets.
But there is some way in which poets believe that and this is dangerous, too believe that their calling gives them a certain freedom. A certain freedom to live in a free way.
The trouble with the performance poets is that they don't seem to have read anything. So there is not a real sense of the poetic tradition in their work.
And I watch my friends, most of whom are in academic life because most poets have to be in academic life, there aren't so many other ways to survive.
