How were slaves treated in Kentucky?

While there was mistreatment of slaves, and slavery is a heinous institution, it is important to note several facts:

The average annual household income in US before the Civil war was about $500 (that's annual).

The cost paid by the Union Army per horse in 1861, $100.

The average price paid for slaves in 1860, $2000.

$2,000.00 in 1860 is equivalent to $52,125.00 in 2013.

The cost of a new 2014 Mercedes-Benz C-Class 4dr Sdn C250 Sport RWD is $50,975.

One does not buy a new Merceds-Benz and enter it in a demolition derby.

The fact is that the vast majority of enslaved blacks in the US had a higher standard of living than most freed blacks, and the greater majority of white laborers and farmers.
