for some time now, a friend of my parents has suffered from cancer. he never told this explicitly, they found out by accident a few years ago.
when his own father died some many years ago, he was the heir to a fortune of real estate. he never sold it or used the money from it; instead he went on and used as little money as possible on himself and on his living. he continued this style of life, always scavenging for offers, always bringing home junk until the house he lived in wall full of it (literally, boxes upon boxes of stuff); he never threw anything out because he thought everything to be of at least some value.
20 or more years might have passed since his father died to present day. he is currently at his deathbed in a hospital. about a year ago, he met this one woman, who seemed interested in him and in caring for his last days of survival. my parents (and i assume he himself) quickly discovered that she was a "gold digger", claiming to serve and help him (but only really doing so when she thought others weren't watching). he never spoke of it; rather, keeping it a secret or a taboo that everyone knew - as with most things he did.
with the inevitable coming on, i think he has finally realized that the money he kept for so long has brought him nothing but misery. he has very few friends left because of his behavior/alienation towards them, and the only love he has had in his life has been one that was out for his money.
money can buy you a lot of things; a new car, a house, "friends" and perhaps "love". but money can never repair you if your spirit is broken. i'd go so far as to say that those people that are shallow, reveling in materialistic greed will never find true happiness. but this is not the fault of the money, but rather of the person using them.
