It's still common practice in the US not to discuss salaries. Which is total BS because transparency on salary can only benefit the workers; the "taboo" nature of the discussion is perpetuated by big companies who try to discourage collective bargaining (btw, forbidding employees from discussing salaries with their co-workers is illegal in the US - despite what your employment contract may say).
