Rather, there are many ways to approach this:
1. Salary negotiation could be included within curriculum at CS schools. (Schools would love if alumni made more money!)
2. Techniques could be included in books (like "Soft Skills"), podcasts, etc.
3. The culture in Silicon Valley could emphasize the importance of negotiating a fair wage.
Left to their own devices, companies WILL exploit those who believe that negotiation is "bad". Companies might not even do so intentionally, but might do so merely by hiring the cheapest employees who have the highest skills.
A side effect is that even if only 75% of employees negotiate to higher wages, the "market rate salary" for employees will increase. If, instead, 75% of employees did NOT negotiate, you'd see a depression in wages.
