In this case, companies will need to "negotiate" with each other, by outbidding each other for top (or at least in-demand) talent. That will set the rates, instead of the current system of imperfect information that works mostly against employees. Let management be the one that worries about offering attractive salaries, rather than the much-less-powerful job seekers.

Some extra laws might be required, such as forbidding and heavily fining companies that are shown to be acting like a cartel when setting salaries. At the very least, if salary offers are public, salary fixing conspiracies (of the type several Silicon Valley companies were fined for) will be much harder to pull off again.
