The people who need to overcome temptation to the highest degree have the hardest time doing it.

The more cashless our society becomes, the more our moral compass slips.

We're actually trying to develop an iPhone app, now that the Droid is out, we'll do it for that as well, if we ever learn how to program on this thing. But the idea is that to make money concrete. So, you can do this app, and it's not out there, but you can do the app. And you say, "I like vacation in the Bahamas, shoes, lattes, and books." And now, when you are tempted to buy something, that thing translates in terms of the things you are interested in.

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.

I don't know what exactly the translation is but when we do consume something now, something else has to give at some point.

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.

When we think about labor, we usually think about motivation and payment as the same thing, but the reality is that we should probably add all kinds of things to it - meaning, creation, challenges, ownership, identity, pride, etc.
