That's just the choices people make. I saw an interesting factoid some time ago. In the early 20th century, it was considered enough to have 7 m2 of living space for an adult and half of that for a child. If people still considered that enough, they could buy homes and be debt free before 30. But because people can reasonably expect to afford more, they take loans against future earnings to buy bigger and better homes. Meanwhile, students live alone in apartments that once housed families.
