At the same time, we can't have this, "the world ends", at the end of every GOP administration either. So we really do need to fix this.
The alternative is we get some different parties, and I've seen little to no indication of that happening. The other parties have neither shown an ability to evoke a response large enough to get elected. Nor have they shown an ability to govern even in the extremely unlikely event that they were elected.
For the foreseeable future, we are stuck with the dem-rep dichotomy. Which can work. We just need for the reps to stop running the nation into the ground when it's their turn. Other nations have shown us that reasonable and effective responses to the pandemic were possible. Why are we here? What is the set of missteps or issues that got us here? We have to identify those issues, and fix them.
