There is a podcast called The Julia La Roche Show. It's basically a series of interviews dealing with macroeconomic and market issues. The host is not particularly good as an interviewer, but that turns out to be more feature than bug as she tends to have smart people on her show and she just lets them talk. Anyway, this is not a recommendation for the podcast in general as there are better ones on the same topic.
However, one recent interview is worth a listen. It's with Scott Galloway (a B-school professor at NYU). I don't think he is right about everything, or really anything in particular, so this isn't an endorsement of his views, but I think what he has to say is interesting and worth listening to. The first few minutes are pretty banal middle class investment stuff, but it gets more interesting.
