Sticky Tastes and Preferences?

After moving my Internet service is now up, but with down times. I hope to be able to start blogging frequently.

This morning, I downloaded an iTunes song from 1975. I willing to opine that most consumers tastes and preferences don't change over time. Maybe, my taste in music is sticky? If so, then consumers would be slow to change buying behavior even in a boom. Now, if consumers become pessimistic, encouraging them to begin spending again will take a long time.

We're all Keynesians now.
