Earlier quoted context omitted.
I've read the book. And all his other books. They're fun, but they're not a great source for serious understanding. The book and movie does briefly explain all this, but it paints a picture that the instruments themselves were inherently toxic, which was not the case. What was toxic were the assumptions that went into modeling their risk characteristics. The assets (like all assets) themselves were fine. The problem…
In that assets are only created for people to purchase with informed understanding, I don't think "they were great but nobody understood them" is a possible thing. The clearest example here is shares in a Ponzi scheme. Those are definitely assets, and they are definitely not fine. They are made to not be understood. The same is more subtly true of the previous wave of essentially fraudulent mortgage-backed securities…
It isn't the case that nobody understands them. We understand them just fine now. This is how civilization learns. For a long time we didn't know how to price options - now we're quite good at it.
> The clearest example here is shares in a Ponzi scheme. Those are definitely assets, and they are definitely not fine. They are made to not be understood. The same is more subtly true of the previous wave of essentially fraudulent mortgage-backed securities. But I think the same is also true of any hard-to-understand instrument engineered to look like a good deal at first glance.
Ponzi schemes are designed to defraud unsophisticated investors. These assets serve a useful purpose and work just fine as long as their risks are properly understood, which they now are.
> You also ignore systemic risk. For many years before the 2008 collapse, cognoscenti knew that a lot of risk had gone somewhere, we just didn't know where. But we sure found out! Saying that "all assets are fine" is sort of like saying "all chemicals are fine". It's technically true, in that dioxin and DDT don't intend to be harmful. But if the evidence shows that people can't use them responsibly, then a ban in a totally reasonable outcome.
The evidence does not show that for these assets. You could make a similar case about basically any dangerous but useful technology. When dynamite was first invented i'm sure a lot of people died messing with it. That doesn't mean we should ban it, it means we need to figure out how to handle it and use it safely. We now understand these assets pretty well. I'll bet you basically whatever amount of money you want that the next crisis will not come from these assets.
