Slavery, right here in New York City

Rico's friend Kema, she of the on-line Slavery Museum, will find this New York Times article of interest, while Rico finds it shameful:

Of all the commodities traded over time on Wall Street, the one that goes discreetly unmentioned in historical markers is human beings— the anxious throngs of kidnapped slaves that the New York City government routinely rented and auctioned off across half a century at the end of Wall Street at the East River.
This omission seems particularly egregious on a street where the excellent Museum of American Finance currently presents all manner of economic history and profit-building commodities, from railroads to cotton.
But no spotlight at all on slaves, even though they were pioneer Wall Streeters— their labor built much of the city’s infrastructure, including the early City Hall, stretches of Broadway, and the signature wall that first defined Wall Street. The city is finally rectifying this with plans for a sixteen-by-twenty-four-inch memorial sign whose wording has not been set, but will acknowledge that the city did indeed run a profitable slave market, rivaled only by Charleston, South Carolina, as a hub for the American slave traffic.
The sign will be installed near where the open-air slave market was erected in 1711, when the municipal government decided to centralize the traffic in the slave trade. These were years when as many as twenty percent of New Yorkers were slaves, their labor making life so much easier for about forty percent of the city’s households. “The blacks we rule over with such arbitrary sway,” was the way George Washington, the nation’s slaveholding patriarch, described them.
Are modern New Yorkers aware of this inglorious history? “Not at all,” says a city councilman, Jumaane Williams, who proposed the marker at the behest of Christopher Cobb, a historian with a passion for details. “This sort of knowledge is generational,” notes Cobb, who feared an enormous fact— that a city slave market operated at the geographical birthplace of American capitalism— was slipping from sight.
News of the memorial was first reported by WNYC, which noted how New York City profited enormously from slave labor, enriching Northerners who bankrolled Southern plantations, then Civil War military suppliers and some big corporations that are still around, like Aetna, New York Life, and JPMorgan Chase. The city was so intertwined with slavery that Mayor Fernando Wood proposed secession as the Civil War approached, rather than lose the rich cotton trade with the South.
Charleston preserved its slave market, and tourists can linger there at informative and poignant displays. In contrast, the memorial sign seems like a mere New York City minute of infamous history. But by midsummer, at least, confirmation of the city’s forgotten role in slavery will finally go public on Wall Street.

Rico says that, just like drugs today, slavery was just too profitable to pass up...
