The numbers you posted do not make this claim. I replicated the significant numbers you posted. Per capita income in the South $103. Per capita income in the North $128. These aren’t MY numbers but YOUR numbers.
BTW Slaver Senatorial testimony is hardly worth the sound it made. And you have to be able to interpret what the numbers say. This you are incapable of doing as your repeated mistakes regarding each statistic show.
Everyone knows there were extremely rich Slavers but that tiny group is overwhelmed by the huge swathes of extreme poverty in the South. Areas where literacy was uncommon and which were basically outside the monetary economy.
No wonder you defend the Slaverocracy you don’t know anything about it.
BTW the Southern wage rates for slaves hired out was NOT as high as you believe.
Your comprehension is lousey.
