According to Silver Spoon Oligarchs: How America's 50 Largest Inherited-Wealth Dynasties Accelerate Inequality, a new report out Wednesday from the Institute for Policy Studies, the country's 50 wealthiest familie from 1983 to 2020 had amassed $1.2 trillion in assets. By comparison, the bottom half of all U.S. households—an estimated 65 million families—shared a combined total wealth of just twice that, at $2.5 trillion.
The fortunes of dynastic families increased at 10 times the rate of ordinary families.
For the 27 families that were on both the Forbes 400 list in 1983 and the Forbes Billion-Dollar Dynasties list in 2020 their combined assets have grown by 1,007% over those 37 years. This is an increase from $80.2 billion to $903.2 billion in inflation-adjusted dollars. In contrast, between 1989 and 2019, the wealth of the typical family in the U.S. increased by just 93 percent in inflation-adjusted dollars.
The five wealthiest dynastic families in the U.S. have seen their wealth increase by a median 2,484% from 1983 to 2020.
In 1983, Wal-Mart founder Sam Walton and his children were worth just $2.15 billion (or $5.6 billion in 2020 dollars). By the end of 2020, Walton's descendants had a combined net worth of over $247 billion, an inflation-adjusted increase of 4,320%.
The Mars candy dynasty has seen its wealth increase 3,517% over the past 37 years, from $2.6 billion in 1983 (in 2020 dollars) to $94 billion by 2020. The family has also spent large sums on public policy advocacy to change tax laws.
Cosmetics magnate Estée Lauder and her descendants have seen their wealth grow from just $1.6 billion in 1983 (in 2020 dollars) to $40 billion in 2020. This is a growth rate of 2,465%.
