I want to know the answer to the following question:
What is an example of something that can be detrimental if too many individuals pursue the same behavior?
All the background I'm provided with is that "Behavior that may be optimal for an individual (e.g., saving more during adverse economic conditions) can be detrimental if too many individuals pursue the same behavior, as ultimately one person's consumption is another person's income.". Is that enough to answer the question?
