>The requirement that all race-conscious admissions programs have a termination point "assure[s] all citizens that the deviation from the norm of equal treatment of all racial and ethnic groups is a temporary matter, a measure taken in the service of the goal of equality itself." Richmond v. J. A. Croson Co., 488 U. S., at 510
If it were about diversity as you claim, rather than righting historical wrongs of inequality, there would be no concept of a termination point of these programs as diversity would be an ongoing concern ad infinitum.
