Abraham Maslow, in 1970, made a pyramid describing our needs. He kept the domino theory in mind while thinking of how he should set up the pyramid. We must feel that we are satisfied with our physiological needs before we can think of getting a roof. Having the feeling of being secured motivates us to seek love. Once we have accomplished the need for belongingness then we seek for a better future which motivates us to set goals and achieve something honorable in life. Once we have accomplished a settled life with love and respect, we might then look to reach our full potential. Most people involved in the hurricane Katrina went from higher-level needs to seeking lower-level satisfaction. Most people around that time cared about nothing but physiological needs, such as water, air, and food. After the storm left its horrific effects and people surviving started to be satisfied with physiological needs, they got motivated to climb the ladder once more and go from lower-levels of needs to higher-levels of needs as described by Maslow.
