But not before it first makes one strong. One at a time, for his or her lifetime, the oppressor is made economically strong by the unfortunate.
One dollar at a time, slow but steady is the contribution of the many unfortunates to the wealth of the few oppressors holding the magic bags of trinkets.
The phones, the pads, the games, the apps, the use of them charged in smart packages, desired by the unfortunates but only afforded on credit.

That's the new face of the oppression; Booker would be glad to see it does not discriminate anymore.
