Pols seem to have difficulty focusing on "long term" and also acknowledging what the results will be of what they pass bill-wise. Why?

 It's as if they live in the moment only. Yesterday they leave behind and learn nothing from it. Tomorrow will never arrive so why spend time on it? Just today. Now. This thing is all that matters. All we have to do is "do it" and it will magically take care of itself. When does ANYTHING ever take care of itself?
