How do wealthy people know if the people they meet are wealthy or not? - Sopuli

For example, if a wealthy person only wants to socialize with and date other very wealthy people, how would they know? Like, for example, what if LeBron James or Tyler Perry only wanted to be friends with other wealthy people and wanted their kids to only date and marry people from other wealthy families? How would they know the people they meet also come from multi-millionaire families? I’m sure if a random billionaire met someone at a club or social event, they wouldn’t introduce themselves by saying, “I’m X, Y, and Z, and I’m worth this much money.” What if a son of a multi-millionaire wanted to date a woman who came from a wealthy family? Also, if he meets a woman, how would he know if she comes from money or not? Like I said, she wouldn’t say, “I come from generation wealth” right off the bat.

They go hang out in incredibly expensive country clubs and on their yachts and at elite universities and prep schools, polo camps and air conditioned safaris.
I had rich grandparents and great grandparents and they didn’t do any of that. The only “rich” thing I remember them doing is going hunting.
I mean, what’s mentioned in this thread is what rich people I know do. Plus saw a lot of it in Palm Beach.
My grandparents never lived rich… my grandfather’s father did build a fortune in Long Island but most of it was lost during the 1929 crash and subsequent Depression. However, what they did do was save and invest and land values were inexpensive in the late 30s so they bought a house for $3K a few blocks from the bay. They always lived really modestly and volunteered, worked civil service type jobs, required all their kids to work after school and really just socked away every dime they could. When my grandmother retired, they bought a condo in Florida and became snowbirds. Our family still has that condo. After my uncle died (he was left the house for his lifetime), his brother sold it for over $600K. The rest of the Trust after my grandparents died was divided among the brothers and survivors of the ones that were already gone. They were never Hamptons rich though.
