Landlessness, a lack of education, social stigmatisation, high mobility, extreme poverty and dependency conspire to prevent San from breaking out of the self-reproducing cycle of marginalisation in which many feel they are trapped. The per capita income of San is the lowest among all language groups in Namibia. The majority of San in Namibia lack access to any independent means of subsistence, and a sizeable proportion of them have no direct cash income. San consequently consider pensions, food aid and other forms of welfare as being vital for survival. In addition, they generally have to pursue a variety of economic strategies for income generation, as rarely is any single strategy sufficient for satisfying their basic needs over an entire year.
