I’m in CA. Interestingly, UC and Asians have a mutual love. But while UC also loves blacks, they choose to attend elsewhere. Check the stats—Asians apply, are admitted, and enroll more than others. Even when admitted to UC, both blacks and whites decline those offers more than Asians do.
And I think Latinos are already the majority of UC students—or will be soon—they are the majority of CA high school seniors.
The largest block in the UCs is still Asian, last I looked. State may be different. CA has two university systems.
