Saving, spending, planning — you've got money questions and we've got answers. Every week host Alison Southwick and personal finance expert Robert Brokamp challenge the conventional wisdom on life's biggest financial issues to reveal what you really need to know to make smart money moves. In this week's show, Bro interviews financial-planning expert Wade Pfau about the assumptions underlying the 4% safe withdrawal rate in retirement, and whether they’re still valid. And Alison discusses whether an elite college degree is worth the price.
