Why does Equiano feel a little better when he hears he will work for white people?

Equiano is initially afraid of his captors and being killed while on the ship, but then he realizes that although he will be working for white men, he will at east have a chance to make some money on his own.

"Equiano's fears eventually subsides somewhat, as he becomes aware that he will not be eaten. He is not afraid of working, and once landed in the new world even does a little side business to make money for himself."
