I don't think this issue of disclosure is about being friends at work, not really. In different venues, I've come across this idea of "bringing your whole self to work", and I think this issue of disclosure falls along these lines. It seems to be the new mantra.

I don't want to bring my whole self to work, I don't want to identify with my job or my company or see myself as part of a tribe. As far as my job is concerned I just want to do good work. And so I really don't identify with this notion.

I would say that at this point, the relationship between employee and employer is generally rather adversarial. I accept the situation such as it is, but I don't relish that. I don't want to bring my whole self to that. I want to wall my real self off from that. I have a job because I need money to do the things I actually want to do. So in that sense, sure "all I want is money". That is a normal reaction to how things are.
