One use of the term cracker is in reference to the one who cracks the whip (i.e., slave driver).
A big problem with slavery is that the slaves are not motivated to work hard. Hence the need for a cracker.
Contemporary crackers are called managers; contemporary slaves are called 'the service sector'; contemporary masters are called Capitalists.
actually, that make sense, hit by the whip on the back, it is a good motivator to get people to work. they had probably lousy minimum wage, back then.
you have a boss that has slaves, you need a good manger to keep your employees. you keep in line, you want to waste a good bullet on them. there is a lot of paperwork having too many graves on your plantation, you what i mean.
the whip is presenting power from who is boss, and the power. also, the whip presenting slavery, because how the black slaves were chain in the gallows of ships rowing boats in middle ages. they were whip and force to row the boat to control them, they were less animals little bit more than human beings.
