Well, at that small amount (which, frankly, I think is more likely for the aforementioned reasons of sales puffery), they could still have financial problems. They have a daughter who is attending a golf school, don't they? Correct me if I'm wrong. That can cost a bit more than 7500. Again, had she been making 75K to 175K, I doubt tuition would break them.
In any case, I still think that BB was the main breadwinner for most of their married lives, bc she was a stay at home. As such, a once a year fishing trip isn't asking too much, IMO, as long as the family is fed, clothed and sheltered. When you consider what some wives spend per year on hair, makeup, nails and clothing alone, I don't think it's fair to begrudge a man a fishing trip! However, this is all conjecture. We don't really know for sure if she did complain about that.
