What do they think the lives of their white grandchildren will be like in such a country?

You assume that it'll be all whites who are going to be displaced.

The white children/grandchildren of the elites will be protected and groomed as future leaders.

You don't think white leftists are going to be subservient to the black/Hispanic/Muslim masses, do you? No, they will be in charge.

It’s foolish to think you can maintain a pre-Mugabe minority style control for very long. The progeny have to go out in the streets from time to time—they can’t all be leaders.

” The white children/grandchildren of the elites will be protected and groomed as future leaders.”

I’ve seen zero evidence that the elites are capable of creating a warrior class amongst themselves to protect their families, wealth and power. They always need to rely on mercenaries for protection. When the money runs out or there’s a power shift or the mercenaries pack and leave the elite’s employ, the elites are destroyed. Happens all the time.
