“But out of this deformed equality was forged quite undeliberately, yet inexorably, a state of affairs which could harness an immense potential in the black woman. Expending indispensable labor for the enrichment of her oppressor, she could attain a practical awareness of the oppressor’s utter dependence on her – for the master needs the slave far more than the slave needs the master. At the same time she could realize that while her productive activity was wholly subordinated to the will of the master, it was nevertheless proof of her ability to transform things. For ‘labor is the living shaping fire; it represents the impermanence of things, their temporality’ [Marx].”
On a societal and (mostly) unconscious level, white men, white women, and Black (POC) men depend on Black women to do the shittiest and lowest paying/no-est paying jobs--in other words, to power and ennable the system that oppresses them. That situation means Black women have the latent and unrecognized power to throw it all into chaos. To destroy it by tearing away the foundation: themselves.
(Obviously the actual process of doing that is more than complicated.)
This is the key sentence:
the master needs the slave far more than the slave needs the master
