An example is that, following the housing crisis, people quipped about how all "those people" who were taking out bad mortgages should have been renting instead of buying their homes, and there are a lot of arguments for why renting is superior to ownership for real estate (repairs done by professionals, more mobility, etc). But few people actually want to live by this. They'll gladly rent in their 20s when they're starting out, but they want to own the house they raise their children in.
