What is the definition of good debt and how can it be distinguished from bad debt?

Good debt refers to borrowing money for investments that have the potential to increase in value or generate income over time, such as student loans or a mortgage. Bad debt, on the other hand, is borrowing money for purchases that do not increase in value or generate income, such as credit card debt for unnecessary expenses. Good debt can be distinguished from bad debt by considering whether the borrowed money is being used to build wealth or improve one's financial situation in the long run.
