The psychology of the saver and the psychology of the investor is very closely connected with Keynes' distinction between risk and uncertainty. When the future is uncertain, he thought that a lot of saving would be directed towards securing, securing more, getting more security in the present, rather than building wealth in the future, which was the classical view, you save in order to invest, in order to consume more later on. What he had called the propensity to hoard or liquidity preference would normally be stronger than the inducement to invest.

What would've happened, do you think, had the government not intervened in October 2008? The catastrophe to the economy would've been absolutely unbelievable. And yet classical economists say, "Oh, well, no, it would've adjusted perfectly happily, a few weeks of pain and then everything would've gone on as before, without a banking system left." And that's what makes it so maddening, that these bankers are back saying it was all the government's fault. The government saved their skins. It didn't want to, but it needed to save their skins in order to save the rest of us.

When you think of everything in terms of just money, then almost nothing is enough. I mean, how much money is enough? Because it's hard to translate money into goods. And I think people, once, I think there's a lot things can believe, and once they start thinking about wealth in terms of money, they lose the idea of enough-ness.

Americans feel as though the only position they can possibly occupy is number one and if they're not number one, well, the end of the world has come.

You do just have to go back to moral philosophy and you've got to say, okay, there is greed, people do want more and more, but then what restrains them and what restrained them in the past was a view of life in which one's satisfaction wasn't the most important thing, that you just, you needed enough and you could say, "Enough is enough." Maybe religion will get you there, maybe just classic moral philosophy, but you have to have some of that, or else you're always on the gravy train.

There's no automatic mechanism in a market system that reconciles the desire to save and the desire to invest. And therefore, the government has to sort of do something or the Federal Reserve, the Fed, or the Central Bank, or whatever, it has to intervene. It has to create enough investment for the economy not to suffer from a fall in aggregate demand. So, if you don't have a balance within the market system itself, then you need an external balance and that's what I think Keynes believed.
