Why is poetry the most demanding literary discipline but worst paying?

[poetica]

with the exception of rap/hip-hop which is a form of poetry...

[GU-UN]

Because there are not many buyers - this is the bitter destiny of poetry and philosophy.
It is even bitter with religion - it is given free, but not many people want to take!
Perhaps, things will change wonderfully when mankind become more mature in the next century.

I do not find it demanding. I refuse to sit down and work out a plan for a poem, its supposed to be from my soul but that is impossible if I am worrying about stanzas, rhymes, how many beats and syllable's. I would never write anything if I had stop and think all the time is my poem correct. Money well.? Rilke says that if you are a poet you have to write and that is true for me.
