This is a podcast about 40 minutes long from Freakonomics Radio. These are the guys that wrote the hugely popular international best seller, Freakonomics. I listen to this podcast regularly. It is pretty great and covers a wide range of topics, mostly revolving around economics, society, and culture.
Below is a link for a show they did called, "Everything You Always Wanted to Know About Money (but were afraid to ask)." Its fairly basic material, but super important none the less. Great listen, and very very worth the time. Check it out:
