I think it is a safe bet that no one's story really applies to anyone else, at least not directly and precisely; it is always a matter of general concepts translating from one person's experience to the more general case.
Remember that this isn't just a parent-child issue, but rather a spouse-spouse issue. When my wife and I got married, we were not on the same footing, financially. Some would say that we "should" have kept our finances separate "just in case" so that if we "didn't last" that we'd leave the relationship with something close to proportional to what we came into the relationship with. Ridiculous. We were making a solemn and heart-felt commitment to each other. For us, equivocating on that commitment by sullying it with a financial overlay, that worked differently from the relationship itself, was an anathema. For us, putting our marriage as the highest priority relationship, even above the relationships with other family members, was a natural.
Not everyone needs to follow the same path -- that's not the point. The point is that that is a reasonable path for people to choose to follow. It is a path deserving of respect: No one else necessarily needs to feel compelled to travel that path, but people should feel compelled to respect the decision of those who decide to travel that path.
