This fails to realize Congress works entirely the way it was designed. As you said, inaction == lack of consensus.
Imaging running a country where significant ways of life (influenced by laws) change willy-nilly depending on the flavor of the day? The legal whiplash would be absurd.
So, people often look to the president as some sort of king analog, and demand action via Executive Order - then cry foul when the next president undoes the previous one's EO's... it's lunacy and not a good way to run a society.
