Growing up neither my parents or friends of my parents talked about specifics around money. Not only how much everyone was paid, but also how much they paid for a car or a house.
When I went to negotiate my first salaried job I had no idea how much to aim for. Was $30,000 a reasonable salary? $60,000? I realized then that everyone's aversion to talking about money had left me in the dark as to how the business world worked.
Why is everyone so hesitant to share their salaries and other financial information?
Note: I know that it is against company policies, at many companies, to disclose your salary. Is there a reason besides this?
Edit: Has sharing financial information, either personal or about your company, ever caused you problems later? I would love to hear some good stories.
