Because of the earning ability gap, the earned fraction of blacks and browns, F B , is always less than the utopian fraction, f B . I define the intrinsic polarization function , p as the difference between the utopian and meritocratic curves. Poster 3 shows how the function varies with the population mix. That is the most volatile mix. The 1999 population mix generated significant polarization, the intrinsic polarization function reaching 53 percent of its maximum value.
Circumstances degenerate as the workforce becomes more black and brown.
The Census Bureau forecast of a 38 percent black-brown workforce in 2048 is also marked on Poster 4. At that mix, the intrinsic polarization function will have increased to more than 80 percent of its maximum value, a dangerous condition. The level of resentment will be way up. As Jim Boyd suggests, that combination of polarization and political muscle could produce destabilizing unrest. My model cannot say.
