White Ashenazi and Sephardic Jews used black slaves as farming equipment
Enslaving black slaves was a net loss for White Gentiles and White Gentiles would be better off if they did their own farm labor instead of enslaving black people to do farm labor
"These Jews, largely immigrants from Spain and Portugal, derived much of their livelihood, directly or indirectly, from the slave trade. Approximately one third held slaves themselves"
