A limitation of this study is that it defines “retirement savings” as money in literal retirement accounts. Due to the perverse structure of how most retirement accounts are tied to employment and the rules around them, there is no vehicle for a significant percentage of Americans to actually put significant savings into retirement accounts regardless of income. As a consequence, a not small subset of Americans have much or all of their retirement savings elsewhere out of necessity. Another subset has a strong preference for rental real estate, which again is outside of the “retirement savings” rubric even though that is literally their retirement plan.
I know quite a lot of GenX that would be impoverished in retirement as defined in this study that are actually quite well off. This is like the oft-quoted study that shows Americans can’t pay for a $400 expense from savings, where “savings” is defined as “literally having a savings account”, which few people even have anymore regardless of income or wealth. It paints a misleading picture.
It would also help if the government didn’t tie retirement saving so closely to your employer. Retirement saving limits should be the same for everyone, regardless of employment.
