Given the wide availability of more complete data points on total comp packages from other sources (eg levels.fyi) it’s unlikely a “government mandated salary database” will add any net new information in many cases, and per above that government salary data will likely be misleading at best.

I do get that the optics look good though and it makes politicians feel like they’re doing something.

Barely published and the US tech sector is looking for ways to minimize its effect or bypass it completely.

levels.fyi is dependent on people willing disclosing, and is of course for very limited sectors of the job market.
