Your mom: Why don't you have a credit card? It helped me so much when I was in your situation.
You, a young adult who doesn't check: I'll get one! runs up debt with an interest rate 4x what your mom had to deal with thirty years ago HELP I'M SUPER BROKE AND BANKRUPTCY IS A LOT HARDER THAN IT WAS THIRTY YEARS AGO TOO
You, a young adult who checks: The interest rates are 4x what they were when I was in your situation. This looks like a much shittier deal than it was for you.
There needs to be a name for the way people think the world hasn't changed since they were a young adult. I'm not convinced it's just boomers; it's just that they had it so good the contrast is higher. Gen Xers do the same thing, I'm sure, for example assuming that kids ride their bikes to school and have textbooks and the leading cause of death isn't GSWs.
