Morningstar has a pretty active YouTube channel that I think has some interesting content.  A good example is an interview with Jack Bogle that is broken down into bite-sized chunks that are easy to watch and provide some great perspective from an industry pioneer. Embedded here is one I really like.

Some gems:

"Managing other people's money is very different from trying to sell other people products and services."

"Investing should be about giving honest-to-God, down-to-earth human beings a chance to accomplish their own goals."

The industry can do this by, among other things, "cutting way back on salesmanship, and moving way up on stewardship...", as well as "cutting back on innovation."

Amen.
