Some poetry serves the "higher" meaning of discussing political ideas like Claudia Rankine's Citizen: An American Lyric.

Some poetry is made to make you laugh like Billy Collins' Another Reason Why I Don't Keep A Gun in the House.

Some poetry is purposefully inscrutable and difficult because the author wants you to work to understand them. A good example of this might be r-p-o-p-h-e-s-s-a-g-r by E.E. Cummings.

Each of these examples is meaningful in its own different way. I think trying to decide what has meaning is hard because you might automatically discard a work of art that is "just for fun". Isn't play meaningful?
