You're going to need a citation for this because every article I've ever read about it says that within 2-3 generations most family fortunes (excluding those truly massive billion+ fortunes) are gone. Social mobility between upper-middle and upper class across multiple generations is incredibly high/fluid.

Even today Norman surnames (compared to Anglo-Saxon/Celtic) are massively overrepresented in the wealthy in the UK, from an event that happened nearly a thousand years ago. Individuals might rise and fall through social/economic classes, but families as a whole are pretty sticky.

Last time I read about this, social mobility is actually quite low right now no matter where you look.
