In poetry there is no trickle down effect. You don't hang a bright light in your garden and tell your plants, Reach for that goal. You water and feed and fertilize all the things growing in that garden and work toward greatness. To create a tall plant, you develop and stimulate the roots.
We don't need fifty thousand dollar prizes so much as the simple act of paying an artist for his work. If you hear or read one moving poem, buy the book. If it has not been published, offer the poet a dollar or two for a typed or hand written copy. He'll be thrilled. Besides, that's where the money should be going.
