Fortunes diluted by too many heirs are largely squandered in a generation or two. If that weren’t the case, I’d likely have been born into wealth myself. I was not, but do have a few ancestors who were wealthy in the extreme by the standards of their day. All I got was a certain grudging acceptance into certain social settings as genteel po’ lol.
Primogeniture laws were unfair but often kept inherited wealth intact. If an estate falls below a certain level of critical mass, it’s much more easily lost entirely due to poor decisions, war or other conditions beyond ones control.
