I like the poem as I can relate. It reminded me of talking with my stepfather who was watched cnn 12 hours a day because his job required him to keep up with the latest news.
But as far as the craft of the poem itself...it is vague and leaves the reader thinking, what was so important that was never heard.
If I was to write the poem, I would have ended it with a line stating that "I" was not important enough, however you would write that would be up to you. I think that subtle change would add clarity to your poem, but whatever you do, the poem needs focus as to what was so important. You have this great momentum going in your poem...but then it never comes to a point...and that would not be hard to do and would add so much dimension to this great insightful poem.
