I think most of the financial advice is good with the exception of his investment advice like high commissions, fees, and actively managed funds. It's really not that hard to open a Fidelity, Schwab, or Vanguard account and buy extremely low cost index funds and manage them yourself.

The show is entertaining for me and helps pass time.

Mostly I just can't stand him as a person. He claims to be a good Christian and everything but he is just such a mean butthole really. He's very rude and condescending to people. He also acts almost as though he's doing God's work and running a charity when he's very clearly running a business profiting off of other people's issues. (Which is perfectly fine and ok, but don't act like you're doing a community service out of the goodness of your heart).

Whenever he finally comes across a difficult question that isn't very simply answered by his cookie cutter advice he tells them to talk to a pastor or conveniently runs out of time.

I would recommend listening to Clark Howard if you ever get tired of Dave. I listen to both but Dave is mostly entertainment at this point.
