|No, not that Hernando de Soto!|
Enron hid its collapse by moving its losses "off the books" to shell companies to make itself look much more profitable than it was. Today, the financial system seems focused more than anything on making instruments like credit default swaps and complex derivatives that are profitable largely because they are so complicated that it's easy to make money from the people who, at least temporarily, don't understand them.
These activities add almost no value to the economy, but they did do a lot to cause a gigantic recession. Despite all that, the financial reform bill Congress passed last year was modest at best, and even those gains are the target of massive efforts to roll them back.
I don't agree with de Soto that the housing price bubble didn't contribute to the collapse, but he makes a great case that the fact that the modern world just doesn't have much of a clue what's going on in the "shadow banking" system is a huge problem that is likely going to cause another meltdown in the future.
