Why captain of industries and robber barons to describe the industrialist?

Another view of the industrialist is that of "captain of industry." The term captain views these men as viewed ingenious and industrious leaders who transformed the American economy with their business skills. They were praised for their skills as well as for their philanthropy (charity).

In reality the debate over robber barons and captains of industry mirrors views of industrialism itself. Just as their were both positives and negatives to industrialism there were positives and negatives to the leaders of industrialism.
