Can you name one entitlement program that has gone out of existence as a result of the parasites being weaned off of it?
Your statement is a bit of the reality that we live in and why we can hope for much but not expect a "full-monty" clean sweep. Things will have to be whittled at and even then the tentacles of entitlements are woven so deep we can only hope for a concerted effort and slow progress.
Your statement also outlines the dilemma we are in and what reality brings to the game - we can either support Trump's efforts and help him do what he can or we can try to condemn hi because the reality is even bigger than him. He's a fighter with our interests in mind - I won't condemn him for "failures" that he cannot achieve on his own and which will be fought tooth and nail by the Dems/RINOs/GOPe.
