Yes, the 300 million or so dollars that funneled annually through the port of New York was produced by slaves. New York didn't care. They just wanted the money. So did the US government. That's why they were willing to write slavery permanently into the US Constitution in an effort to keep that sweet sweet slave revenue flowing into their pockets.
And Lincoln supported this amendment. Apparently slave money was more important to him than slave freedom, but what else could you expect from a "Globalist" I mean "Mercantilist" President?
Only 20% at most "funneled" through New York.
The balance shipped directly from Gulf Coast ports to their European customers.

No, what Lincoln said was he didn't believe such an amendment necessary, since the Constitution at the time implied it.
So your proposed amendment here was just one of many different ideas to "compromise" with Deep South secessionists.
None produced positive responses from Confederates and all came to nothing.
