How do the visions of kennedy and johnson differ from the vision of roosevelt?

Kennedy and Johnson lacks focus on issues concerning people at the grassroot, while Roosevelt's vision was to regulate the economy and guarantee justice.

Explanation:

President Johnson's Democratic reform program project great society measures, including Medicare, civil rights legislation, and federal aid to education. And Kennedy's New Frontier policy was designed to enable the cold war by proxy in Central America.

Kennedy and Johnson did not gave focus on issues that concerns farmers, workers and students.

Roosevelt passed several acts that benefited the grassroots. He insisted that the economy and justice can be regulated as a major priority of the federal government. And that a President can achieve a successful economic agenda by the protection of human welfare.
