I, too, am pessimistic about our chances. But some folk who are more read up than me about it (e.g. Jamille Bouie, Helen Cox Richardson) express more optimism, citing trends and moments in history that rhyme.

Although, I am worried that our ultra-wealthy are exponentially richer than the robber barons ever have been at any other time in history. Once they're done financializing the US into a wasteland (of quarries, oilfields and data centers), they're going to move onto the rest of the developed world, and they are rich enough to buy all the elections and control all the governments.

So if we can make our stand here, and recognize our billionaire class as the existential threat that they actually are, (and as Paul Krugman suggests, tax them out of existence) we'll be sparing the entirety of human civilization a lot of devastation.
