>> It's sad how much of a difference money makes. Ideally, money would have no bearing on love or marriage. I'd like to think that if I was well-off (or if my spouse was) and then something disastrous happened, that we would still support each other throughout.

Marriage are bonded over factors more than love and people in love get divorces. The money aspect of the study is simply showing that the more money a couple has the less likely non-love factors are able to break up a marriage. Seems completely reasonable to me.
