> It's also just dirty pool: employers seek to shame / threaten employees to not share compensation data (and, in circumstances where state laws do not prohibit this, terminate employees for discussing comp), and then want to have all the data themselves. It creates a very tilted negotiation field.

I have done quite well for myself. But I am concerned that this is one more way that the field is tilted against disadvantaged groups. Past history of being discriminated or of screwing up negotiation stays with you indefinitely, and that's not great. The data asymmetry is not great, either.

Peoples' personal financial information should not be aggregated and shared with employers without their consent.
