The fifth lesson is that not all innovation leads to a more efficient and productive economy - let alone a better society. Private incentives matter, and if they are not well aligned with social returns, the result can be excessive risk taking, excessively shortsighted behavior, and distorted innovation. For example, while the benefits of many of the financial-engineering innovations of recent years are hard to prove, let alone quantify, the costs associated with them - both economic and social - are apparent and enormous.
Indeed, financial engineering did not create products that would help ordinary citizens manage the simple risk of home ownership - with the consequence that millions have lost their homes, and millions more are likely to do so. Instead, innovation was directed at perfecting the exploitation of those who are less educated, and at circumventing the regulations and accounting standards that were designed to make markets more efficient and stable. As a result, financial markets, which are supposed to manage risk and allocate capital efficiently, created risk and misallocated wildly.
