Gen Z is living with their parents to save money. But it's going to cost them, big time.

After graduating from college in 2021, Bethany Clark moved back in with her parents. She planned to spend a year studying full time to be a teacher, so it made sense to live at home in Surrey, England, while she wasn't earning an income. But when she landed her first teaching job the next year, she didn't leave. "I didn't see the point in moving out without any savings," she told me. Two years later, at 24, she's still living with her parents and plans to stay for another year, maybe two.
