I experienced this myself. My dad went into the family business, and had another job offer waiting (in a small town) when they sold that without having to be interviewed. I never learned how to really network or do stuff like that in college, and it definitely impacted my opportunities and such. I never even realized how important it was until I went to an "elite" college, where it seemed like all the other (read: those whose parents had to, or were raised much more well-off than I was) students knew how to. I was kinda at a lost because the university often assumed we knew it too, and so let it go by without necessarily teaching us.
