I like openness as much as the next guy, but it is really nobodies business to know, how much I earn, except for my employer, the tax office and myself. Don't forget your co-workers. Capitalism only works with information transparency. The minute there's an information asymmetry, things break down. In this case, without information about the salary of your co-workers, you cannot effectively negotiate for your own value, which puts you and all of your colleagues at a disadvantage to the employer. Of course, that's really the American way these days, but that doesn't make it a good thing.
