Here we are talking about families with children leaving San Francisco, and that can't be addressed on it's own merits. No diversity actually trumps when the problem is addressed. '...essential to a diverse thriving city.' This should read, '...essential to a thriving city.'
The big sins here are, older, more wealthy, and a more White city. You've got evidence of prejudice against the elderly, the wealthy, and Whites.
Leave out the wealthy and White portion of this, and it is reasoned to address the elderly because you need replacement people in any society. Add those in, and ageism becomes something of a problem too.
God forbid a subject of importance be raised without racism and prejudice rearing it's ugly head.
I would not advocate for a Whites only town, but if that is the eventuality, it's not a crime against nature. It would have happened because Black families made choices that were theirs to make. There could just as easily crop up a town that was all Black. Big whoop. Who cares.
Families with kids are leaving San Francisco. Who could have seen that coming? LOL, they made their own bed, now let them sleep in it with whoever they want, and shut up.
Let me guess what's next here. They'll start subsidizing Blacks with children who will move back into town. I'll bet this was the main goal all along, to justify the unjustifiable.
OK... New Obama mandate. You can’t leave San Fran if you have kids or we will only let you move if you are moving to San Fran.
