Why was slavery the basis for economic freedom and success in the colonies?

Have you heard of Nathaniel Bacon? He would promise them, and low payed workers freedom and respect if they helped him rebel against Berkeley, and his companions.

well first we can compare on what the slave masters ate and what the slaves ate well the masters ate fancy great food like chicken rice mash potatose and stuff like that and slaves ate well food that your not suppost to eat like the weird parts of turkey and chicken and slaves master chilled beat and eat and slaves work get beat and get little of sleep there you go

it was bribing i think i might be wrong though
