Inflation-adjusted wages for employees in the middle of Silicon Valley’s income ladder declined between 12% and 14% over the past 20 years, The (San Jose, Calif.) Mercury News reported. According to a study from UC Santa Cruz’s Everett Program for Technology and Social Change and the labor think tank Working Partnership USA, technology workers saw a median wage increase of 32% over the past 20 years. However, Silicon Valley workers in virtually all other areas lost ground during that time; across all jobs, wages for even the highest-paid 10% increased just under 1%, the study found.
