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.

Our student loans were around 1% interest while a man in another shiny tower would give 4% interest. So the logic here is to borrow from one to lend to another.

There's a trick with credit cards which might not work in all countries. You max out one credit card, get all the loyalty benefits and free flights, then pay it off with another credit card before any interest is charged. I guess nobody feels bad about ripping off the man in the shiny tower.
