This past week I had a "light-bulb" moment after viewing the movie 
"Amazing Grace" about William Wilberforce's campaign against the British
 slave trade which was abolished in 1807.  I began to realize exactly 
what that "trade" was all about, and it wasn't 'pretty'.  This movie 
actually happened during Jane's life time and she knew of the writer 
Hannah More.
 
I was checking James Austen's periodical, "The Loiterer" that I put on line, for a quote and ran across this in Issue 23
 subtitled "Vexations attending the pursuit, and possession of wealth, in a letter from Indicus.":
 
The Son of a  Neighbour (very few years older than myself) about this time returned from the East-Indies,
 with one of those sudden fortunes, which  never fail to draw upon their
 possessors the admiration of the Vulgar, the envy of the Weak, and the 
pity of the Wise. — As we had  been formerly Schoolfellows, and our 
Families were still upon terms of great intimacy, I was one of the first
 who were invited to a  magnificent Villa, he had just purchased, on the
 banks of the Thames, where one fortnight spent amidst the luxury of 
fashionable  dissipation, and the blaze of Oriental Grandeur, completely
 turned my head, and determined me to waste no more time in this dirty  Island,
 but to go at once to that Country, were riches were so easily to be
 acquired. It was to no purpose, my Friends attempted to  oppose this 
resolution: it had so entirely taken possession of my mind, that it 
haunted my very Dreams. Sometimes I found myself carried in  an elegant 
Palanquin, attended by a long train of Blacks; and at others inclined at
 my ease on a rich Sopha, while my careful Slaves drove  away the 
Mosquitoes with their fans. I now settled the accounts with my Circars, now counted imaginary Lacks, and admired the lustre  of ideal Diamonds.
 
My
 point being that James Austen used the terms "Blacks" and "Slaves".  So
 the Austens must have had some idea about that situation.  However, I 
am not at all sure what James means with the term "Lacks".
 
The
 movie left me in tears and consternation at the ignorance of us 
"Southerners" (in the U.S.) of the real circumstances of the People of 
Africa.  I am here to declare that slavery is
 wrong and evil.
 
The complete Issue No. 23 gives us a good example of what should and should NOT be done with wealth.  You may read it HERE.
