Arguably, freelancing or starting your own business will continue to be the best way to achieve this (and it comes with considerable risk), as your negotiation skills and business acumen will contribute to your income, as well every other skill not directly connected to the job description for a specific role.
At a full-time, salaried job, though? Do you get a higher salary because of your demonstrable value, or just because you've become a great salesman? The latter being why tech companies throw up barrier after barrier in their hiring process to try and differentiate between smooth talking and genuine skill (or value).
The point being, would you even work for a company at all knowing where you stand as a freelancer, or a consultant? From where I'm standing, publishing the payroll wouldn't make a jot of a difference.
