My guess is those problems were largely domestic in effect, so a)not as relevant to foreign policy and b)difficult to represent given the fact that Home countries are not contested areas.
That was indeed the rationale. However, by way of demonstrating that there were no purely domestic/international questions during the Cold War, the Civil Rights movement used the international card in the debates over the Civil Rights Act. It was argued to some effect in Congress that in order for our system of government to be attractive, and for us to lead the "free world" we had to address the racial inequities in the United States. It is also surely true that the Soviets tried to exploit our domestic difficulties for propaganda value.
