The true statement about Richard Nixon and Lyndon Johnson’s social and economic policies is:
B. Johnson supported Medicare and the Civil Rights movement, while Nixon supported state block grants and created stagflation.
Lyndon Johnson is well-known for his Great Society programs, which included the establishment of Medicare as well as strong support for civil rights legislation. Richard Nixon, while he did implement some social policies, also presided over a period of economic difficulties, including stagflation, and he advocated for state block grants, which gave states more control over funding social programs.
