Abraham Maslow was a psychologist concerned with the nature of the human experience,
a humanistic psychologist. In 1943 he proposed a theory that described the different needs that all humans have and the hierarchy in which those needs are organized.
According to Maslow, higher-level needs cannot be satisfied unless lower-level needs have been satisfied.
From the bottom of the hierarchy upwards, the needs are: physiological, security, love and belonging, esteem and self-fulfillment.
Each person is capable and willing to move up the hierarchy to a level of self-realization. Unfortunately, progress is often interrupted by not meeting the needs of a lower level.
Life experiences, including divorce and job loss, can cause a person to fluctuate between the levels of the hierarchy.
These needs of the Base of the Hierarchy: Food, Shelter, Security and Education are in "theory" guaranteed not only in the Universal Declaration of Human Rights, but in most of the Constitutions of the countries.
Surprisingly none of these needs, studied by Maslow and even written in the UDHR, are satisfied by any government, in order to keep the population at the Primitive Levels of Maslow's Pyramid of Needs.
