The white man’s happiness cannot be purchased by the black man’s misery.

Comfort built on somebody else’s suffering is not a stable kind of comfort, and it is not really happiness either. Where one race’s ease is paid for with another’s misery, the damage does not stay with the people who pay: such an arrangement corrupts the people it favours as surely as it harms the people it exploits. That is a harder claim than the usual appeal to sympathy, because it does not depend on the beneficiary feeling generous.

Look at the arrangements you are inside, at work or further out, and ask who absorbs the cost of your convenience. You may not be able to change all of it. Knowing the answer is still different from not knowing it.
