Hi John -- Last time I checked, poets were valued at $11.39, but that was on Fox News, so I'm not sure about the reliability...
Poets are of value in the same way that artists, painters, sculptors, composers, novelists, essayists, and even experimental video freaks are of value.
There has been a division between arts and science for the past hundred fifty years or so, but it seems to be an artificial division. Was DaVinci an artist or a scientist; Schroedinger a scientist or a visionary, and on and on.
Poets and scientists, and any one else who puts their notions out into the world enhance our understanding of ourselves and our environment.
Of course, lousy poets don't enhance it much, and neither do lousy scientists.
This theme has come up in a number of your threads, and I think you're trying to get at something on a fundamental level. I'm not sure, though, that it is all that complicated.
