I think that consumerism is intrinsically a pretty flawed social system.

I became a vegetarian 55 years ago, and I think it's one of the more important behavioral changes I ever took. The more I see of the beef industry and so on, I believe that to be true.

I'm part of the consumer culture. I was part of the baby boom generation. I have a car when I shouldn't, a couple of computers I can't be anti-consumerist in that sense.

What people say often precedes what they think. Some people sometimes say, I have to hear myself talk before I know what I think. I think language sometimes, because it opens new channels, it opens new doors, is enormously important.

Any prudent business looks at the reality and how to maximize our investment.

Companies watch what consumers are doing like a hawk. Just as one letter to a politician can signal an insipient problem, for companies, a trend where people are beginning to switch away from one of their key products to a rival offering on the basis of either claims or real improvements on performance, that's significant.

Behavioral change is more important than individual product choices. They both have a role to play.
