Both major parties benefit from the status quo of Congress being incapable and everything being ephemeral—each can promise their stakeholders that if you elect them this cycle they'll make sure that things go their way for this cycle. The ephemeral nature of the "win" is valuable because if they actually made a permanent fix the urgency to elect party Y would be gone. It's the subscription model applied to governance.
My theory is that if you remove the administrative law game, things will quickly get broken enough that stakeholders will demand better, so both parties will get their act together and actually try to pass legislation again.
It's entirely possible that I'm wrong (and cue the inevitable "it's not both sides" comments), but unless something unexpected happens to the court system it looks like we'll get to see in a few years.
