Northerners' reasons for accepting slavery in the South had nothing to do with its profitability, or lack of, but rather with their commitment to the Constitutional compromises engineered in 1787.

Do you think the power masters of the New York elite gave a crap what the general public thought?

Don't be naive. The people that mattered wanted that 200 million dollars per year.

See my post #1,140 above.
It notes that your number of $200 million represents the total New York investment in Southern slaves, which was at risk of forfeiture from secession.
And that's a big number, but remember the total value of all slaves in 1860 was put around $4 billion of which New Yorkers' $200 million was only 5%.

Also, your $200 million number represent roughly all cotton exports in 1860, but of those no more than 20% went through the port of New York.
The rest shipped directly from Gulf Coast ports like New Orleans, Mobile and Galveston.
