I found the first one. It was called "Stewardship Of The Air", available at Brother Brigham Challenges the Saints - Stewardship of the Air I found Hemidakota's second guess, and it's not what I was looking for either. As I've been thinking about it, I remembered a specific part. Towards the beginning, he said something that went something like this. Not an exact quote, but something along the lines of: "I frequently hear students talking about how Jacob 2 says that if they're righteous, that they are justified in seeking wealth, that 'after ye have obtained a hope in Christ ye shall obtain riches, if ye seek them,' and that since they're righteous, worthy members of the Church, that that means it's OK to go out and get rich. They're missing the point of the verse, which is that 'ye will seek them for the intent to do good—to clothe the naked, and to feed the hungry, and to liberate the captive, and administer relief to the sick and the afflicted.' It's about taking the resources that God blesses you with and using them to help others. Amassing a personal fortune is never part of the program." Not the exact words, probably not even close, but that's the sense of what he said towards the start of the talk, and then somehow he got off on Gadiantons and businessmen. I hope this can help someone direct me towards the right lecture? Thanks to everyone who's offered suggestions so far!
