“Children from sibships of 1–3 typically left less wealth than they inherited. But children of families of 7–12 left nearly twice as much wealth as they inherited.”
Fascinating since larger sibship size usually predicts lower IQ, lower education, lower income.
So is it that large sibship in wealthy families inherit the platform without the cushion? They have every advantage except $$$$. high social capital, low financial capital.
Raise your kids hungry but give them every tool, I suppose.
The wealthiest wealthy families substantially converge to the mean across generations, but nevertheless remain very wealthy relative to merely rich families and the population at large.
They can be expected to remain above-average for ~10-12 generations.
