A lot of the problem is that the party of business as usual (Democrats) doesn't have answers for the problems business as usual caused.
Even the re-emergence of a business as usual Republican party wouldn't help. They were part of the problem too.
Something has to change - but the response to Bernie Sanders showed the obstacles to that. Even if they wanted to, Biden and Co. are incapable of the kind of reforms that could undercut the lunatic right. There is no way to genuinely make America great again.
With options to the left precluded, only rightist options are available.

Please ignore the following. I'm just being mad.
The best way to restore the viability of capitalism as a whole would be to have a Really Big War. Nuclear war is still bad though. A war with China might work, but is risky. A war between Russia and the EU (with the US somehow staying out of it!) might be preferable. (Who cares if some Poles and Germans get nuked!) Then the US can swoop in to rebuild the European economies, with their competitors eliminated.
So, yeah, the US needs to withdraw from NATO. This is sufficiently idiotic that it would take a Trump to do it.
That's how to Make America Great Again.
It's OK, I'm taking my pills now...
