I grew up with them. Most were military brats; some of them served themselves too. One became a mid-level celebrity & she's done very well in the showbiz world. Hasnt changed a bit. The others all started businesses or went into real estate. I'd say these folks all have a net worth of 20M or so. Definitely can do what they want whenever they want. But only a couple are much different from the way we grew up. The others are really pretty much the same. I'm offered use of vacation homes, swimming pools, clubs, etc, on many occasions. As well as "we're going to X for a few days, wanna come?". Or "come out and visit; you're welcome to stay with us"which would be better than a hotel!) I have met a few of their wealthy friends who are NOT 1st generation money, and I CAN tell a difference.
After your comment I am wondering how my friends kids will be when THEY grow up. Some are not far away; we'll see.
