Plantation Workers Not Slaves

One should recommend that the history that African blacks at the slavery time should be referred to as Plantation Workers alternatively with Slaves. These African blacks working in the field and plantation contributed enormously to build America wealth and economic prosperity. So to respect their humanity they should be referred to as Plantation Workers as such and not Slaves all the time. This can start in teaching students in schools.
Admittedly the African plantation worked very hard and if they did not thy were swvwely punished and possibly flogged.
