Thousand-page bills, unread and indeed unwritten at the time of passage, are the death of representative government. They also provide a clue as to why, in a country this large, national government should be minimal and constrained. Even if you doubled or trebled the size of the legislature, the Conyers conundrum would still hold: No individual can read these bills and understand what he's voting on. That's why the bulk of these responsibilities should be left to states and subsidiary jurisdictions, which can legislate on such matters at readable length and in comprehensible language.
As a corollary to this, where in the Constitution does the federal government derive the authority to legislate a healthcare mandate?
