What is the difference between “good debt” vs. “bad debt”?
When I look at debt I try to think of myself as a corporation.  In life, you have a series of projects that you can undertake which may yield a positive net present value (for simplicity, let's define positive net present value as a project that yields more benefit than its cost). Let's say that one of the projects that you have is to build a factory to make clothing.  The factory will cost 1 million dollars and will generate revenue of 1.5 million dollars over the next year, afterwhich it wears out. Although you have the knowledge to build this wonderful factory, you don't have a million bucks laying around, so instead, you go borrow it from the bank.  The bank charges you 10% interest on the loan, which means that at the end of the year, the project has yielded a return of 400k. This is an extremely simplified example of what you call "good" debt.  It is good if you are taking the debt and purchasing something with a positive value. In reality, this should be how people should approach all purchases, even if they are with cash.  Everything that you buy is an investment in yourself - even entertainment and luxury items all could be seen as an investment in your happiness and relaxation.  If more people approached their finances in this way, people would have much more money to spend, William
