I feel like it is a mistake to assume all families will teach (or know) these skills. It seems like that assumption could perpetuate inequality. I was fortunate enough to be raised by two parents in a stable environment but that wasn't the case for some of my friends and cousins. They ask me for advice on buying a car, getting a mortgage, building credit, investing, etc. Some don't even understand why you would save money ("Isn't that what social security is for?"). They call me "the adult" but I was just lucky enough to have a father familiar with these concepts and willing to talk about them.
