Amidst all the confusion, finger-pointing and bad news, we forget to realize that this recession has a reason - a fairly deep and simple one, at that; a contradiction, a false assumption that led the world into this. In the acuteness of a suffering state, the true reason is harder to see, because unexpected suffering begets indignation, indignation begets anger, and anger requires an external cause to be angry at. But the true deep reasons for this crisis are not negative aspects of human nature such as greed, or misaligned incentives of financial managers, or the policy of Federal Reserve, although for sure all of these played a part.

The true deep reason is a benign, yet shortsighted and naive, desire that most people would consider justified. It is the desire for a secure and prosperous retirement.

What fails to be emphasized is how both the tech stock bubble and the housing bubble could not have happened if it was not for an overwhelming deluge of funds, a deluge which exceeded the supply of worthwhile assets to invest in. These funds came from all over the world and were, all things considered, money belonging to savers everywhere. It was money belonging to people who would not consume today the results of their work, but wanted to postpone their consumption until tomorrow, or the day after tomorrow. In the case of the tech stock bubble, it was money that people hoped would be multiplied. In the case of the housing bubble, it was money that people hoped would be invested safely until it's needed.

The lesson to be learned from this crisis is that the safe and lucrative investments that savers everywhere are looking for, do not exist in numbers large enough to cater to all.

When a large population is being persuaded that they should invest someplace and get a long-term return larger than GDP growth, it is a hoax. It is physically impossible for an entire population of savers to enjoy future returns that are better than GDP growth.

As a saver, one is staking out a piece of the future economy, and wants to get as large a slice as possible. It is not possible to get a slice larger than the entire economy. But the entire population, as a whole, owns the economy. It is not possible for the entire population today to own more than the entire economy of the future. Hence, everyone's investments, on average, cannot grow faster than the economy.

This crisis has a reason, and the reason is... everyone was trying to find a place to invest their money and get safe, above-average returns. It turned out that such places are illusions. Yes, production capacities still exists; yes, factories still stand; yes, we have the means to create everything we were creating before this. But what we were creating was consuming the money of people who thought they were saving, but were in fact giving it away.

If no government had intervened, this lesson would have reached the ultimate causers of this crisis: the hundreds of millions of bank depositors who think that saving is as simple as stashing your income at the bank, and seeing interest roll in. As it is, governments did step in; as a society, we apparently want depositors to be able to maintain this illusion.

This is bad. If people understood that it is their propensity to save that caused this crisis - that the problem is the world's inability to accomodate that many savers and give returns - they would not react to this crisis by saving more. Instead, they would spend. And spending today, not tomorrow, is exactly what is needed to make the economy zoom again.

But given that governments are committed to sparing depositors, the state of the economy makes people save more, so more of their money stays in banks. This money could again be spent, to get the economy going, if only the banks would lend. But the banks have been burned, so they lend less than they used to, and the money just sits there. This will make the economy grind quite a bit slower for a while, until banks become confident enough to lend again.
