Deadlock is the point, less is more, worse is better.
The Court could choose to act with the knowledge that Legislative won't do things, and so behave as the last bastion of relative non-partisanship across the Federal government by allowing the overall public opinion to influence what cases they choose to hear & their eventual outcomes. That would conflict with the letter description of their job, but arguably be in support of the spirit of the system as a whole.
They're not going to go that route, though, it appears.
