Finance != Economics. Financial dumbassery can impact economics and economics will improve finances, there’s a relationship but they aren’t the same thing.
People learned the long lesson from the energy crisis in the 1970s, choosing “supply side” economics, which is putting the financial sector in charge of economics, and that’s resulted in an upside down economy. People learned the wrong lesson from the energy crisis, should’ve learned to end our dependence on oil, but people got bamboozled into thinking Reagan good and Carter bad. Now we’re in a situation where we can’t make the economy function properly because half the electorate is convinced the anything other than supply side economics is literally communism, and a significant portion of other half of the electorate is becoming convinced that they should support other failed economic policies in opposition to the failed supply side policies.
Many of the economic problems we’re facing have happened before, and instead of considering those policies (trust-busting, Keynesian economics, taxes on the wealthy) you’re presented with a choice between different paths to economic failure.
It’s what Marxism is about isn’t it? Leftism is heavily influenced by Marxism, you hear leftists often say “late stage capitalism” without thinking how stupid the implications of that phrase are. Constant references to Star Trek abound, without realizing that show is actually agnostic on economics, they use an ideal system, but the writers don’t know what that would be. “Post-scarcity economy” is another phrase that’s used often.
Overall this indicates leftists don’t actually know anything about economics, they’re just unhappy with how things are going and have no idea how to fix it. Not significantly different than the MAGA movement, just putting faith into narratives that feel right to them.
