I heard an interview with Michelle Singletary, the financial columnist at the WaPo. All 3 of her kids live at home, so they can save money.

A year after getting her master’s degree and doing an internship in Texas, our eldest moved home and is saving the vast majority of her yearly income. At 27, she’s plowing 15 percent of her gross pay into her 401(k). She’s saving up to pay cash for an electric vehicle in about three years.
Our son graduated from college last year and is still living at home. He’s working two part-time jobs while studying to enter the actuarial field. We are in no rush to see him go. He’s lovely to have around — plus he’s the main dog-walker.
My husband and I agreed not to charge any of our children rent as long as they are saving, so that when they finally launch they will have a substantial cushion that should keep them from boomeranging back home.
