I have Sun trine Jupiter and it's true, I'm satisfied and happy with what I have no matter how much or how little I actually have. I keep a lot of things that I have for a long time and I generally like something the same amount, if not more, as time goes by.
I think other indicators of being satisfied with one's wealth is Moon-Jupiter (trine/sextile), Venus-Jupiter (trine/sextile), Mars-Jupiter (trine/sextile), Mars-Saturn (trine/sextile). I think having various combos will create the overall feeling of content.
