It might not be quite what you have in mind, but
The Survival Podcast actually has a big focus on killing debt and making life both more simple and more secure at the same time. The host is a pretty outspoken guy who may not appeal to everyone (he does most economic shows from a libertarian point-of-view) but if you like to garden and have any interest at all in self-sufficiency it might be more up your alley than you might originally think. The podcast's tagline is "Making your life better if things get tough or even if they don't" and I'm often surprised that a show on emergency preparedness can be as positive as it is.
