What concept describes different levels of needs being satisfied according to income?

Maslow's Hierarchy of Needs is a psychological theory that categorizes human needs into a five-tier model, arranged in a hierarchical manner from basic to more complex. According to Maslow, individuals must satisfy lower-level needs before they can address higher-level needs. The five levels, from the most fundamental to the most advanced, are physiological needs, safety needs, love and belonging needs, esteem needs, and self-actualization needs.

This concept can be directly linked to income because as individuals earn more, they often have the means to satisfy higher levels of needs beyond basic survival. For instance, someone with a lower income may struggle to meet their physiological needs such as food and shelter, whereas those with a higher income may focus on social belonging, esteem, or self-actualization, such as pursuing education, hobbies, or traveling.

The other theories mentioned, such as Freud's psychosexual stages, Erikson's stages of development, and Skinner's conditioning theory, do not specifically address the concept of needs being met relative to income. Freud's approach is centered around childhood and psychological development, while Erikson focuses on psychosocial development across an individual's lifespan. Skinner's theory revolves around behavior and conditioning, not needs hierarchies linked to income
