Both sides keep spending money because everyone wants spending brought under control, EXCEPT SPENDING IN THEIR OWN BACKYARD OR FOR THEIR OWN PET PROJECTS! Let's face it, no one is willing to make the sacrifice to get spending under control because they feel "the other guy" is not making the sacrifice, and hey, as long as he's getting his, I'm gonna get mine, too!
I very much agree that something needs to be done, but where do you start when constituencies seem to want their elected pols to "bring home the bacon?" Not being facetious - really, where do you start?
