This episode of Marketplace Weekend is all about generations and how who we are, from the Greatest Generation to Generation Z, shapes how we live with money. Starting with retirees and working our way to high school students, we take a look at generations in the economy, our psychology and our wallets. The U.S. Peace Corps is actively recruiting boomers. Why? Rosemary and John Bottcher explain. They served in the Peace Corps in Paraguay from 2011-2013 when they were both in their late 60s. Later, Marketplace Tech host Ben Johnson talks with Lizzie about what instant messaging says about how your generation communicates. Plus, Marketplace Weekend visits John Marshall High School in Los Angeles to talk with four college-bound seniors about how their lives and their generation are shaped by money.
