The civil war improved the economy of the north, but harmed the economy of the south. The south relied heavily on agriculture/ producing cotton on slave worked plantations. The civil war led the slaves to finally be freed thus sending many southern farmers into poverty.
The development that probably hurt it is the reduction of open range herding. In history, people could just let their cattle roam freely and find food since the plains were huge and nobody lived in them. Nowadays, this can be problematic because there are more and more people and settlements and roads with cars so free range herding has been drastically reduced which cost the herders a lot.

The correct answer to this open question is the following.
Although there is no source document attached or any other reference, we can say that Henry Wallace’s background and previous disagreements with President Truman might have biased his thoughts because Wallace had a different political perspective as the former Presidential Candidate of the Progressive Party. His own point of view and political tendencies made Wallace bias his opinions and criticized the way President Truman acted during the Cold War years. Wallace had been Truman's Secretary of Commerce but never get along well with Truman. Wallace's liberal approach biased their opinions about Truman's decision to change the New Deal legislation and the foreign policy to contain Communism.
