You also need a healthy emergency fund because roofs and furnaces don't last forever.Hard money - you better know what you're doing and how you're going to get out from under that debt if you're paying that much interest.

As a fan of RK, and being a capitalist myself, I have to admit one must maintain a healthy dose of skepticism when a capitalist lays out a strong or controversial position on a topic, then works in a product or service to sell you that coincides with that position (much like when a socialist makes the argument that centralized power, under their control, is for your own good).
