The South had long been rich in natural resources, but the slave system had been unfavorable to their development.

南方长期以来自然资源丰富，但奴隶制度一直不利于他们的发展。

As long as the slave system lasted and planting was the major interest, the South was bound to be sectional in character.

——只要奴隶制度持续存在并且种植业是主要利益，南方就注定是分裂的。

Thus national economic policies, which could not by any twist or turn be confined to state control, drew the slave system and its defenders into the political conflict that centered at Washington.

因此，国家经济政策不能通过任何扭曲或转向局限于国家控制，将奴隶制度及其捍卫者卷入以华盛顿为中心的政治冲突。
