I can see it as a foreign adversary psyop (they benefit from us being demoralized) or as a side effect of the attention economy (more clicks is all that matters) or even a hyper-partisanship epiphenomenon (whichever side is currently down wants people to think everything is awful).
But "our misery is some potential investor’s financial prospect" sounds like some schlock B-movie plot. How is that supposed to work? Are they secretly feeding creatures from the 4th dimension by harvesting misery or something?
