The more prosperous and capable members of the middle class shared to some extent the benefits resulting from negro labor. Many that had been unable to secure servants now bought slaves and thus were able to increase very much the output of their plantations. The shortness of the time that the servants served, the great cost of transporting them to the colony and the risk of losing them by death or by flight, had made it impossible for the small farmers to use them in cultivating their fields. Since negro labor was not attended with these objections, many planters of humble means bought slaves and at one step placed themselves above the class of those that trusted to their own exertions in the tilling of their fields. When once a start had been made, the advance of their prosperity was limited only by the extent of their ability and industry. Some became quite wealthy. Smythe, writing in 1773, stated that many of them formed fortunes superior to some of the first rank, despite the fact that their families were not ancient or so respectable. Those members of the middle class who were unable, through poverty or incapacity, to share the prosperity of the early years of the 18th century were injured by the general use of slave labor in the colony. Since they could not purchase negroes, they were in a sense thrown into competition with them. The enormous increase in the production of tobacco brought down the price and made their single exertions less and less profitable. They were deprived of the privilege of working for wages, for no freeman could toil side by side with negroes, and retain anything of self-respect. Thus after the year 1700, the class of very poor whites became larger, and their depravity more pronounced.[222] A Frenchman, travelling in Virginia at the time of the Revolution, testified that the condition of many white families was pitiful. "It is there," he said, "that I saw poor people for the first time since crossing the ocean. In truth, among these rich plantations, where the negro alone is unhappy, are often found miserable huts, inhabited by whites, whose wan faces and ragged clothes give testimony of their poverty."[223] It is certain that this class was never large, however, for those that were possessed of the least trace of energy or ambition could move to the frontier and start life again on more equal terms. Smythe says that the real poor class in Virginia was less than anywhere else in the world.
