I too am a Ramsey 'fan' and I appreciate his methods. And seen the title I wanted to write the very same, Yes!!!

I've also worked in many banks in my life and feel that giving 1% and taking 25% interest is insane. Pay every loan/credit card, then keep saving and investing, and you will never need another loan in your life.

A friend has been doing exactly that and bought a house (40yo dude, married, 2 kids) and paid cash for the house and the refurb. He never had a loan/credit card in his life.
