My few encounters with the richly inherited folks were pretty negative. One coworker in her 30s was so spoiled and obnoxious that it made me sick. She seems to have no reservations on anything, i.e, did pretty much what she wanted, revolted if things didn't go her ways, etc.. Another man often boasted about his dad's wealth, e.g "my dad has a mansion with 13 bedrooms." Engaging them even in small talk was difficult b/c they'd talk about things that I have no clue at the time (in late 20's, big mortgages).
I had a co-worker something like that. He didn't make a whole lot himself, and his wife was on disability, and watching kids "under the table", but his parents had money, and the father was always pretty generous in bailing them out.
Well, in 1999 they decided to combine households, selling the parents' house and their own townhouse, and having a nice, big house with an in-law suite built. At that point, they also had seemingly free reign on the parent's money.
I remember one time, commenting about having to put $1000 in repairs into the '85 LeSabre that Grandmom gave me when she had to give up driving, and he commented, dismissively, that I should get a new car and "Life's too short to drive crap!"
He was also a definite "keep up with the Joneses" type of guy. About a year earlier, one warm spring day in early 1998 I drove my '67 Catalina convertible to work, and we went out to lunch in it. He fell in love with the idea of a convertible so quickly that he took their truck and traded it in on a Chrysler Sebring convertible...his wife wasn't too pleased about that!
Still, he was a nice guy. But you could tell he was definitely getting out of touch, in some ways, because of his family's money. Also, when his father died, his Mom wasn't nearly as loose with the money, and their life of luxury evaporated. They had to downsize from a $660K house to a $270k house around 2003, and then lost even that. Last I heard they're both on disability, as he had a pretty bad stroke, and now they're living down in Appalachia somewhere.
