Those aren't significant concerns in the US. Land is cheap and the number of slaves can easily feed everyone; I believe the ratio was at its worse 1 farmer to 1 nonfarmer.
Land might be cheap, but land was also limited. Much of the area around the plantation would be forested in some way.
Do you have a source for the 1:1 figure on a plantation? It seems somewhat dubious, even with children/elderly/house slaves factored in.
... then it has nothing to do with the issue.
Well actually it does, as you see, the point (which I have been labouring over and over, almost to excess), is that slavery was not cost-free labour. I.e., the Southern planter was not just making cash without expenditure.
Because he did not grow or produce much that he needed himself, particularly that with which to sustain his aristocratic lifestyle, he was not necessarily at so massive edge to the Northern industrialist as is sometimes supposed.
Northerners were affected by it as much as plantation owners.
As I said, this was not the case.
The South managed to keep doing this even after the civil war, so their method of cotton production was hardly unsustainable.
Unsustainable does not necessarily mean an immediate collapse, rather that yields would fall year on year until a plantation would eventually become unsustainable.
Yes, cotton production continued in the South. I did not mean that it didn't. The advent of pesticides/mechanical farming and the like helped keep yields up (and even increased them) thus avoiding the slow decline that was inherent in methods. I'd also note that the sharecropper/smallholder had far less outgoings than your average planter. A planter had to buy slaves, care for them, house them, care for his own needs (which were far from modest), hire staff, etc... A smallholder meanwhile needed to grow or buy food for himself and his immediate dependents and maintain their shack.
However, there were also shifts in location of production. If one considers the location of modern production one can see large changes from the highest concentrations of slaves.
That isn't about serving their way of life; it is about making investments that pay off. That is straight up an economic motivation.
Indeed, that is a factor. One would hardly expect railroads in the middle of Arizona at this date. But as I said, this was not an industrial use of the railroad rather an agrarian one. The South as a whole was not pursuing a modern means of making increased profit, rather a traditional one that was not as lucrative.
In terms of cash, I think you are right, but I think what you are missing in the comparison is the huge amount of money it would take for a non-slave owner to match the luxury and pampered lifestyle of a plantation family.
A slave owner would have how many "house servants"? 10? 20?
While slaves had no "cash cost", in a non-slave system cash would have had to be found to pay them....and probably twice as many, because wage workers don't work 24/7/365 like slaves. Nor do they provide the other "benefits".
A valid comparison would look at how costly 30 or 40 workers, used as house staff, would be as a cash cost equivalent.
I think you overestimate the lot of the Northern worker and underestimate the maintenance of a house slave (these in particular would require treatment coming towards that one might expect of a human being).
You also seem to miss my point (as everyone seems to be doing). The detailed point is that slavery was not without expenditure or hazard, in short that it was not simply a massive money making exercise pursued purely for profit. The wider point is that, rather than being a purely economic system, slavery also owed a great deal to social-cultural factors largely centered on the incredible racism (even by the standards of its day, when the good guys also tended to be racist assholes) of the Southern Whites in general and the plantation owner especially. This racism largely found voice through fear, and was subsequently carried throughout Southern society, even though the vast majority of Southerns were not slave owners and an even greater majority not largescale slave owners.
Thats hand-waving.
How much CASH would it take to hire <for wages> that staff?
Based on the extreme degree of luxury they enjoyed, plantation owning families were incredibly wealthy.
Again, I'm not arguing that they were not.
However, let's do the maths on a butler (presumably one of the higher paid domestic roles.
Both are live in and 24/7.
The free butler is paid, the slave purchased, inherited, or raised.
The free butler buys his own clothes, the slave does not.
Both are fed by their master.
Both are housed by their master.
The free butler is already educated, the slave butler presumably so if inherited and likely bought.
The difference in expenditure is not so great after all. Certainly the Northern butler is probably more expensive, depending on wages and inheritance of the slave. However, as I've been stressing, the slave butler is also not without his outlay.
