Why did people think slavery was dying in 1790?

In the early 1790s, slavery appeared to be a dying institution. Slave imports into the New World were declining and slave prices were falling because the crops grown by slaves--tobacco, rice, and indigo--did not generate enough income to pay for their upkeep.

The Northern states abolished slavery. The Southern states had too much money invested in slaves already to go that far.
