How did southern white progressives excuse the practice of black disfranchisement?

the difference is that white collar worker performs skills like worker as a scientist or well blue collars do physical work and they do services like being a cook.

the answer to fill in the blank in this question would be the word resource, it is defined as the money, material or people (since human resource is a very valuable good) that a company or a person has at disposition (meaning they can use the resource as they see fit), to be able to complete a task or achieve a goal.
