It was *absolutely not* merely about $ for Napoleon or the US Founding Fathers.
Napoleon specifically framed it as a question of racial domination. He called it the "Black Specter" & saw it as a threat to white supremacy. Everyone in the white colonial world discussed the Haitian Revolution constantly. They were *obsessed*. Jefferson was terrified.
Haiti's black citizens defeated Napoleon's military efforts to re-enslave them. He promptly sold Louisiana to the US dirt cheap, doubling its size.
