The typical Walmart today offers you 100,000 products.

There is a different attitude about, you know, how much differentiation there needs to be between our options and how many choices do I need to have in order to make a choice.

Knowledge should be a public good, and I want my ideas to have as much exposure as possible.

I used to go to this store called Draeger's and you had a little bit of that same feeling because this was a store that offered you so many varieties, things you'd never contemplated before, you know like 250 mustards and vinegars and over 500 different kinds of fruits and vegetables, or over 2 dozen different types of water.

This is at a time when you know most of us drank tap water, so I used to go to this store and examine all the varieties and we used to marvel at all the choices out there, but I found that I rarely bought anything and I kind of thought that was kind of curious. I mean, they had things that the other grocery stores didn't have and yet I never bought anything.

People will make worse financial decisions for them if they're choosing from a lot of options than if they're choosing from a few options. If they have more options they're more likely to avoid stocks and put all their money in money market accounts, which doesn't even grow at the rate of inflation.

We make choices and are in turn made by them.
