I'm tempted to say that the uselessness of Congress is in indication of something else - we've pushed too much to the federal level. The decades-long tooth-and-nail fighting over healthcare makes me think that an effective system just can't be done federally; there's too much disagreement between states. Why not scrap most of the social programs, cut federal taxes, and let states implement their own?
Or alternatively, that the federal government, as it currently operates, is simply no longer up to the task of modern governance. Too slow, too reliant on voluntary compliance, and most importantly, too difficult to make decisions with long term time horizons.
Not sure you want an efficient, consolidated government if the wrong party is leading it.
