I live with three housemates. Three of us also have significant others, meaning there are seven people in and out of my house regularly.
Of those seven people, five of us have some kind of debt: student loans, credit cards or a mortgage. Sadly, our numbers reflect the average American: the average American household carries $15,611 in credit card debt, $155,192 in mortgage debt, and $32,264 in student loan debt.
Despite the fact that everyone seems to have some kind of debt, debt is not normal.
