Which does not describe an economic problem facing the US at the end of the civil war?

The Civil War has been something of an enigma for scholars studying American history. During the first half of the twentieth century, historians viewed the war as a major turning point in American economic history. Charles Beard labeled it “Second American Revolution,” claiming that “at bottom the so-called Civil War – was a social war, ending in the unquestioned establishment of a new power in the government, making vast changes – in the course of industrial development, and in the constitution inherited from the Fathers” (Beard and Beard 1927: 53). By the time of the Second World War, Louis Hacker could sum up Beard’s position by simply stating that the war’s “striking achievement was the triumph of industrial capitalism” (Hacker 1940: 373). The “Beard-Hacker Thesis” had become the most widely accepted interpretation of the economic impact of the Civil War. Harold Faulkner devoted two chapters to a discussion of the causes and consequences of the war in his 1943 textbook American Economic History (which was then in its fifth edition), claiming that “its effects upon our industrial, financial, and commercial history were profound” (1943: 340).
