Well, off the top of my head, black folks, asians, and latin folks might be more likely to be caretakers and/or further from the office.
That said, if they have Apple salaries, I'm sure they can work it out.
That said (again), they might need to spend more of that Apple salary than their peers to figure it out.
So, it's a bold and unsubstantiated statement, but might have some truth to it. Idk, wish they would cite sources.
