I'm afraid that's not how employment markets work. As an employee you are in a competitive environment and worth what at least one employer is willing to pay you. How that relates to the value you generate for the employer is largely irrelevant in an employer's market and that is what we have today. If you want to price based on value then you might consider a different path that leads to more of a B2B relationship such as entrepreneurialism, contracting or freelancing. The traditional alternative would be something like unionisation and collective bargaining but I don't see that happening effectively for software developers any time soon.
