Lyndon Johnson saw his Great Society as a plan to alleviate the poor of the country from the cycle of poverty through reforms that encouraged public education. Most of the Great Society programs focused on education and job training.

Johnson also created "Project Head Start" which was a antipoverty program that sought to improve the performance of the underprivileged in school by creating pre-school programs for children whose parents could not afford local pre-schooling. Johnson also created Medicaid which was a governmental financial assistance program for adults with children with physical or mental handicaps.
