Do We Actually Need Debt?

Is there such a thing as "good debt"? And how could something good cause so many issues? On top of this is there any way that we could just run an economy without debt and would we be better off for doing so. Well, it turns out we probably can, and in fact, there are many economies around the world today that are developing rapidly while going without this system that we just assume is a given. If we can critically explore these questions it will offer insight into how our modern financial system works, and why it means that despite our best efforts we are almost destined to go into a recession once every 10 years or so.
