I don't think this "information asymmetry" thing will work out well for the workers. What if there are some people who are more productive than others, but have the same job title? Do they really want to hear "yeah we pay you less because you are less productive"? Or vice versa "yeah, you work twice as hard as Simon, but you have the same job title, so he still gets the same pay, sorry". Those social actions all sound very good, but I think people can sour on it quickly when they realize they are the ones who effectively pay for their unproductive colleagues that can't be fired.
I don't think that will go down well, and will just make things more difficult to run.
And the impetus is still "socialist", equal pay for everybody, businesses are exploiting people and so on, those are socialist talking points.
