The way I think about it is that it'll affect those most that are the most greedy, those that are exposed to the most risky "products". If your wealth is in bonds or something else boring, won't this be a non event?
I'm not convinced it's not someone in the background choosing wrong (greed) that's the problem.
You're right. I guess it depends on many variables. If you're income depends on dividends and gradually selling offs of your portfolio, I can see now how that would affect my behavior. Same with being someone close to retirement but then, financial planning should have pulled out high volatile stocks from a portfolio that needs to get converted to cash shortly.
If you're a normal person, planning on buying and holding broad market ETFs for the next 20 years, we're just gonna ride it out, right? Right?
