The average age of U.S. investors with $25 million or more has fallen by 11 years since 2014, to 47. Their numbers have more than doubled since the financial crisis, to about 172,000, aided by the boom in new technologies and venture-capital funding. Meanwhile, the share of wealth belonging to Americans over the age of 65 hasn’t kept pace with the growth in their numbers, suggesting “a vast generational transfer of wealth,” according to Bloomberg. The wealth of “typical” Americans aged 35 to 54 has dropped by 41% since the Great Recession.
