Well, let's say, you "can" gain big money in stock market, also you "can" win big money in casino, both of them have no guaranty but may let you lose big money too. You won't expect big interest return for any banking savings, but the risk is way lower.
Another example, car accidents happen everyday, but plane crash isn't, yet once it happens it has a much bigger chance that a lot more people would be killed. This is what you called "rare events that hurt the most", which is very true. However, I would say since it rarely happens, I consider riding in a car is more risky than taking a plane.
And, I think Lehman was a financial service corporation/investment company but not an official bank. Am I correct? |
