What is the main message in Sociology for the South by George Fitzhugh?What is the main message in the sociology in the south

The main message of this book was that slavery was a
system that was good not just for whites, but for blacks
also.

Fitzhugh argued that slavery was the most just
economic system possible.  He argued that a "free" society was one that was inherently
unfair to the bulk of people.  He argued that such a society made the rich extremely
rich, but allowed them to simply ignore the plight of everyone else.  This was a very
impersonal society in which no one cared about the poor and the
weak.

By contrast, a slave society was very caring.  Yes,
some people did become very wealthy.  However, unlike in a free society, these people
took responsibility for the weak (the slaves).  They cared for those people and made
sure that they had a decent standard of living.  Because of this, the slave system was
much more humane than any system of free labor.

This
defense of slavery was the main message of this book.
