>Why are you confident it will suppress wages?

The same mechanism you see uncoordinated price fixing, companies set their numbers by copy+pasting from their competitor +/- a little depending on the details.

I think noncompetitive companies will be forced to increase wages initially to compete but after that initial spike the numbers will become much more sticky.

Raising the floor is I think is a major win.

Numbers right now are already sticky, I'd argue.

> When _everyone_ is posting the wages, it lets companies at the top end use it as a _______________

a) method of colluding to depress wages

b) PR for "high wages" using jobs they don't intend to fill

c) ...

There are likely many different outcomes and each isn't likely mutually exclusive.

Pretty much every higher paying company already knows that. Even the lower paying ones do.

> this is wrong take, once higher paying companies find out they could pay less due to competitors, they will.

Companies already functionally share compensation information via companies like Radford. You pay a hefty fee and provide your company's info, and in return you get descriptive statistics of the market.

Google and facebook don't scour job boards when determining pay scales, they pick some percentile of the market per these surveys and set compensation at that level. As a result, the companies already have transparency, employees do not, so they can only really gain.

Companies all know what other companies are paying for positions. They provide and collect this information from services that aggregate these details. The information deficit is entirely on your side.
