My dad just never pays things off early. He'd rather pay $10 a month and rack up $5000 interest over a few years than just pay the whole balance. Therefore, he has a lot of debt, while still having plenty of cash on hand. I'm not saying it's a smart way to go, but he's never been denied credit for anything and still maintains a pretty solid standard of living while also being able to provide for his family. As someone who has benefitted greatly from it, I'm not complaining. He seems to have things under control.
