Very happy that our paper received the DFA Prize for Best Paper in the Journal of Finance. The literature on wealth inequality has been highly influential in public debates, yet it largely ignores a key way households save over the life cycle: Social Security. We show that including the fair value of accrued benefits in wealth substantially mutes the rise in wealth inequality since 1989. Its importance has grown dramatically over the past three decades. In 1989, Social Security represented only 26.0% of the wealth of the bottom 90%. In 2019, this percentage rose to 49.8%. We cannot understand household balance sheets without paying attention to Social Security.
