Has there been any response from Bay Area local governments? I would imagine it might not be their favorite idea that businesses are trying to incentivize employees to leave. If this sort of idea takes off, would local gov try to counter these incentives to leave in some way?
This is one of the richest areas in the US and the overwhelming sentiment is, "we need people to stop moving here". You can actually get votes here by making it harder for companies to hire, on the theory that traffic, pollution, etc. won't be that bad.
It's unlike any other place in the US. Truly one-of-a-kind.
