The most important problem is your class warfare arrogance argument based on your ignorance of the real culture of the pre-antebellum South. There were wealthy farmers in the South, as well as wealthy manufactureres in the North. There were massive homes in Biloxi and Mobile as well as in New York, Boston, and Providence. That coupled with the belief the practice of slavery justified killing anyone innocent or guilty essentially made the invasion of the South an act of righteousness for a new morality. And that is expressed by your comment "all men are created equal", a comment not in the US Constitution, and not a legal justification for any action of the government.
"And are you saying that the government was in the slave trade business or are you trying to say that private Northern concerns were in the international slave trade business?"
Private Northern concerns were in the slave trading business while the US government, legally bound to stop the trade, largely overlooked it for 45 years.
"In any case, what was the point in saying that 'Lincoln's new job would pay a salary financed by money raised from the sale of slave produced goods?' ".
To point out to you that a moral imperative, so fundamental to your arguments, did not exist for Lincoln or belong to the government as you so readily believe and accept.
The US Constitution was written by moral men with concepts of morality as underpinnings of the document. They never envisioned, nor wrote law, to allow one section of the country to impose their concept of morality on the other.
