The question is incomplete I am guessing that the statement is \"Liberty and monopoly cannot live together\"

The statement made by Henry was appropriately valid at that era. Monopoly gave a lot power other than profit to any company. At this era there were giant corporations run by individuals.

Human resource as a concept was not even born at that time so people used to work their with no liberty at all.
