The white rulers of the Carolinas seemed to be conscious of the need for a policy, as one of them put it, "to make Indians amp; Negros a checque upon each other lest by their Vastly Superior Numbers we should be crushed by one or the other." And so laws were passed prohibiting free blacks from traveling in Indian country. Treaties with Indian tribes contained clauses requiring the return of fugitive slaves. Governor Lyttletown of South Carolina wrote in 1738: "It has always been the policy of this government to create an aversion in them [Indians] to Negroes."

Part of this policy involved using black slaves in the South Carolina militia to fight Indians. Still, the government was worried about black revolt, and during the Cherokee war in the 1760s, a motion to equip five hundred slaves to fight the Indians lost in the Carolina assembly by a single vote.

Blacks ran away to Indian villages, and the Creeks and Cherokees harbored runaway slaves by the hundreds. Many of these were amalgamated into the Indian tribes, married, produced children. But the combination of harsh slave codes and bribes to the Indians to help put down black rebels kept things under control.

It was the potential combination of poor whites and blacks that caused the most fear among the wealthy white planters. If there had been the natural racial repugnance that some theorists have assumed, control would have been easier. But sexual attraction was powerful, across racial lines. In 1743, a grand jury in Charleston, South Carolina, denounced "The Too Common Practice of Criminal Conversation with Negro and other Slave Wenches in this Province." Mixed offspring continued to be produced by white-black sex relations throughout the colonial period, in spite of laws prohibiting interracial marriage in Virginia, Massachusetts, Maryland, Delaware, Pennsylvania, the Carolinas, Georgia. By declaring the children illegitimate, they would keep them inside the black families, so that the white population could remain «pure» and in control.

What made Bacon's Rebellion especially fearsome for the rulers of Virginia was that black slaves and white servants joined forces. The final surrender was by "four hundred English and Negroes in Armes" at one garrison, and three hundred "freemen and African and English bondservants" in another garrison. The naval commander who subdued the four hundred wrote: "Most of them I persuaded to goe to their Homes, which accordingly they did, except about eighty Negroes and twenty English which would not deliver their Armes."

All through those early years, black and white slaves and servants ran away together, as shown both by the laws passed to stop this and the records of the courts. In 1698, South Carolina passed a "deficiency law" requiring plantation owners to have at least one white servant for every six male adult Negroes. A letter from the southern colonies in 1682 complained of "no white men to superintend our negroes, or repress an insurrection of negroes…" In 1691, the House of Commons received "a petition of divers merchants, masters of ships, planters and others, trading to foreign plantations… setting forth, that the plantations cannot be maintained without a considerable number of white servants, as well to keep the blacks in subjection, as to bear arms in case of invasion."

A report to the English government in 1721 said that in South Carolina "black slaves have lately attempted and were very near succeeding in a new revolution… and therefore, it may be necessary… to propose some new law for encouraging the entertainment of more white servants in the future. The militia of this province does not consist of above 2000 men." Apparently, two thousand were not considered sufficient to meet the threat.

This fear may help explain why Parliament, in 1717, made transportation to the New World a legal punishment for crime. After that, tens of thousands of convicts could be sent to Virginia, Maryland, and other colonies. It also makes understandable why the Virginia Assembly, after Bacon's Rebellion, gave amnesty to white servants who had rebelled, but not to blacks. Negroes were forbidden to carry any arms, while whites finishing their servitude would get muskets, along with corn and cash. The distinctions of status between white and black servants became more and more clear.

In the 1720s, with fear of slave rebellion growing, white servants were allowed in Virginia to join the militia as substitutes for white freemen. At the same time, slave patrols were established in Virginia to deal with the "great dangers that may… happen by the insurrections of negroes…" Poor white men would make up the rank and file of these patrols, and get the monetary reward.

Racism was becoming more and more practical. Edmund Morgan, on the basis of his careful study of slavery in Virginia, sees racism not as «natural» to black-white difference, but something coming out of class scorn, a realistic device for control. "If freemen with disappointed hopes should make common cause with slaves of desperate hope, the results might be worse than anything Bacon had done. The answer to the problem, obvious if unspoken and only gradually recognized, was racism, to separate dangerous free whites from dangerous black slaves by a screen of racial contempt."

There was still another control which became handy as the colonies grew, and which had crucial consequences for the continued rule of the elite throughout American history. Along with the very rich and the very poor, there developed a white middle class of small planters, independent farmers, city artisans, who, given small rewards for joining forces with merchants and planters, would be a solid buffer against black slaves, frontier Indians, and very poor whites.

The growing cities generated more skilled workers, and the governments cultivated the support of white mechanics by protecting them from the competition of both slaves and free Negroes. As early as 1686, the council in New York ordered that "noe Negro or Slave be suffered to work on the bridge as a Porter about any goods either imported or Exported from or into this City." In the southern towns too, white craftsmen and traders were protected from Negro competition. In 1764 the South Carolina legislature prohibited Charleston masters from employing Negroes or other slaves as mechanics or in handicraft trades.

Middle-class Americans might be invited to join a new elite by attacks against the corruption of the established rich. The New Yorker Cadwallader Golden, in his Address to the Freeholders in 1747, attacked the wealthy as tax dodgers unconcerned with the welfare of others (although he himself was wealthy) and spoke for the honesty and dependability of "the midling rank of mankind" in whom citizens could best trust "our liberty amp; Property." This was to become a critically important rhetorical device for the rule of the few, who would speak to the many of «our» liberty, «our» property, «our» country.

Similarly, in Boston, the rich James Otis could appeal to the Boston middle class by attacking the Tory Thomas Hutchinson. James Henretta has shown that while it was the rich who ruled Boston, there were political jobs available for the moderately well-off, as "cullers of staves," "measurer of Coal Baskets," "Fence Viewer." Aubrey Land found in Maryland a class of small planters who were not "the beneficiary" of the planting society as the rich were, but who had the distinction of being called planters, and who were "respectable citizens with community obligations to act as overseers of roads, appraisers of estates and similar duties." It helped the alliance to accept the middle class socially in "a round of activities that included local politics… dances, horseracing, and cockfights, occasionally punctuated with drinking brawls…"

The Pennsylvania Journal wrote in 1756: "The people of this province are generally of the middling sort, and at present pretty much upon a level. They are chiefly industrious farmers, artificers or men in trade; they enjoy and are fond of freedom, and the meanest among them thinks he has a right to civility from the greatest." Indeed, there was a substantial middle class fitting that description. To call them "the people" was to omit black slaves, white servants, displaced Indians. And the term "middle class" concealed a fact long true about this country, that, as Richard Hofstadter said: "It was… a middle-class society governed for the most part by its upper classes."
