In total, by giving people $30 bonus, Intel lost almost 5 percent of productivity. That's a lot. Now, think about it. You give money because you think this would increase motivation. It actually decreases motivation.

Money are very difficult to think about. So, we think about money as the opportunity cost of money. So, we at some point went to a Toyota dealership and we asked people, what will you not be able to do in the future if you bought this Toyota?

For all of us, it's very hard to think about money, and because of that, we need help. In the same way that for all of us, it is hard to eat well, and we need some help. The poor have a particular challenge, which is that their life is actually much more complex - and they're much more complex cognitively.

Once we start thinking of ourselves as polluted, there is not much incentive to behave well, and the trip down the slippery slope is likely.

Who would you trust right now? Which bank would you trust? Which investment would you trust? Do you really want to put your money; do you want to suffer more of these losses that we just had?

So, we hold more money back, we don't necessarily want to invest in the market and by default, people are saving more.
