It will be really difficult for all individuals to share their salaries if some of them are on low salaries and fear not being able to scale up if they publish those.
There's also an intrinsic bias in sharing salaries in that the well-paid folks are more likely to share theirs because they feel validated by the value itself.
We are also on this side and on the job boards we run [1], the companies are required to publish real salary data™ (and we also gather stats based on that).
What is real salary data™ - contrary to the flawed regulations in a few states, which basically allows putting something like 1$ - 100'000$, we require companies to be more specific and have a max range of 30-40k.
Interestingly, the majority (approx. 2/3) of companies are completely fine with publishing this information (if they are forced to) and out of the remaining 1/3, half can be convinced, and the other half is a lost cause (basically, management will not allow it)
