Well, Congress is only able to abdicate their responsibility because we have departed from our "Constitutional design." All 3 branches now write law, not to mention other unelected government agencies, so Congress is now free to avoid doing their job and point the finger at someone else instead.
Not to mention our new 4th branch of government: bureaucracy. They do tremendous work, but I don't think they should have the power to draft regulations that have the force of law.
