What is the difference between “good debt” vs. “bad debt”?
I think people are conflating two orthogonal sets of terms. Unsecured/secured and good/bad are not synonyms. Debt may be secured or unsecured. If I take a loan against a car or house it is typically secured, so the object is collateral against the loan. Bad debt in financial terms is a loan that is not expected to be recovered. A bank might write off a loan or a portion of a loan as bad debt if the borrower goes bankrupt or into administration for example. Both secured and unsecured loans may be considered bad debt. I think the context in which the question is being asked is how to distinguish between sensible and inadvisable borrowing. An extreme example of inadvisable borrowing would be to buy a PC on a store card. PCs devalue very quickly and a store card may charge 30% APR, so paying the minimum off each month would mean paying  more than twice the sticker price for a product that is now worth less than half the original borrowed amount. On the other hand, a 3% mortgage when borrowing less than 60% of the value of a property is a good bet from a lender's perspective, and would be a good debt to have (not as good as no debt, but better thhan a high APR one).
