The ruling classes saw the peasants' right in commons as a source of economic independence from capitalist and landlord, and thus a threat to be destroyed. Enclosure eliminated "a dangerous centre of indiscipline" and compelled workers to sell their labor on the masters' terms. Arthur Young, a Lincolnshire gentleman, described the commons as "a breeding-ground for 'barbarians,' 'nursing up a mischievous race of people'." "[E]very one but an idiot knows," he wrote, "that the lower classes must be kept poor, or they will never be industrious." The Commercial and Agricultural Magazine warned in 1800 that leaving the laborer "possessed of more land than his family can cultivate in the evenings" meant that "the farmer can no longer depend on him for constant work." [Thompson, The Making of the English Working Class, 219-220, 358]. Sir Richard Price commented on the conversion of self-sufficient proprietors into "a body of men who earn their subsis- tence by working for others." There would, "perhaps, be more labour, be- cause there will be more compulsion to it." [Marx, "The Expropriation...."].
