Different answers for different buyers once you get past Maslow's first two levels of needs.
First there are the physiological needs, the base of the hierarchy. These needs are the biological component for human survival. According to Maslow's hierarchy of needs, physiological needs are factored into internal motivation. According to Maslow's theory, humans are compelled to satisfy physiological needs first to pursue higher levels of intrinsic satisfaction. To advance higher-level needs in Maslow's hierarchy, physiological needs must be met first.
Physiological needs include: Air, Heat, Clothes, Hygiene, Light, Water, Urination, Food, Excretion, Shelter,
Sleep and Sexual Intercourse
These physiological needs must be met for the human body to remain in homeostasis. Physiological needs are critical to meet the very basic essentials of life. This allows for cravings such as hunger and thirst to be satisfied and not disrupt the regulation of the body.
Once a person's physiological needs are satisfied, their safety needs take precedence and dominate behavior. In the absence of physical safety – due to war, natural disaster, family violence, childhood abuse, etc. and/or in the absence of economic safety (due to an economic crisis and lack of work opportunities) these safety needs manifest themselves in ways such as a preference for job security, grievance procedures for protecting the individual from unilateral authority, savings accounts, insurance policies, disability accommodations, etc. If a person does not feel safe in an environment, they will seek safety before attempting to meet any higher level of survival.
Safety needs include: Health, Personal security, Emotional security, Financial security.
So pretty much anything you can sell that meets basic needs will probably do well. Once people get past the first two basic need layers it becomes kind of an individual thing with regards to what a person thinks they need or what they want.
