        the University of North Carolina, has a copy of Helper's book that he himself owned, and in the margin, after the Civil War, he wrote: for proof that this book was not written on behalf of negroes, as is sometimes charged, but on behalf of white people, see pages blah, blah, blah.
Helper's critique is that slavery is bad for Southern whites. It has nothing, so he doesn't care particularly about the oppression of blacks, the institution degrades and makes impoverished Southern whites.
That is all you need to know before reading this book.
