Professor: What are the constraints of your study on income inequality?
Student: Probably the small sample size.
Professor: Any constraints with your proposed solution?
Student: Hmm…the only people who can help poor people are the offspring of rich people, and only during a gap year.
Professor: Anything else?
Student: All volunteer opportunities must be Instagrammable.
Professor: Good, good…your work has a nice grasp on human incentives and behavior.
