@Ernest BywaterWhile I love the joke, on a factual basis, for them to be doing a 'much better job' if they were that smart, you'd have to assume that the average moron could solve the problems we face as a nation. I'm pretty sure that's a hard 'no'. If the problems we faced weren't fairly difficult, we wouldn't be dealing with them.
I agree with the statement that Congress should be doing a better job, mind you, just not that the average moron could do better.
One of the complicating factors is that we're now so polarized that solutions which are simple and sensible become impossible because 40% or so of the population will reject them out of hand because they violate some precept of their side. And, since each side tries to cover as much ground as possible, that's true of nearly every issue.
That polarization is the entire nation reverting, as an average, to being 'the average moron', or worse. As long as we keep voting for people because of the letter after their name, and as long as followers of both parties declare people outcast ('RINO', etc) because of the tiniest deviation from the most hardcore interpretation of their side, we're not going to get a lot better.
We used to be able to compromise. Unfortunately, the absolutists have made compromise a dirty word, while pushing ideological constraints that mean they'll never be able to propose a working solution themselves.
