I agree with most of what is said, but I think the word "dysfunctional" is incorrect and implies the wrong characterization of these situations. Show me the entrepreneurs who came out of childhood situations where fighting, alcohol and drug abuse are the norm? I would agree that many entrepreneurs come out of childhood situations where their family struggled through chaotic situations (characterized by uncertain future, time spent living on the margin, etc.), but that the key element is that the family can remain functional and successful in these conditions, thus being closer to the exact opposite of what is normally categorized as "dysfunctional". I can point to the many cases of first generation immigrants who go on to be successful entrepreneurs. Their parents, as immigrants, faced exactly this sort of chaotic situation and had to find a way to remain functional.
