It's the influence of Big Finance, a world in which magical thinking really does work regardless of fundamentals...until the bubbles pop.
The real economy, on the other hand, is just real people who can't afford basics anymore and have no significant savings. The idea that ordinary folks are figuring in future market fluctuations when many of them don't even know who's the PM, is nonsense. If it's Tuesday, they're thinking about how to survive Tuesday.
Optimism is useless to them.
