Why were back-country settlers such an annoyance to colonial government?

As the colonies grew, so did the population of people in the back-country as the planters grew in prosperity and power threatened to shift from the low country. Before this time, the back country settlements and farms had remained small in comparison to the low country plantations. Therefore, the low countries interests were seen as being more important in the decisions made for the benefit of the colony. The back-country settlers were such an annoyance to the colonial government because they didn't want to be part of a government grounded in low country interests.
