Marc Hoffman, a former Army officer who served in Vietnam and spent his career in commercial real estate, joins the show to discuss his book ”Rant” and his years-long effort to investigate oil price swings after Hurricane Katrina. He lays out his view that major Wall Street firms influenced oil prices in the years leading up to 2008, and argues that the recession drove the mortgage collapse rather than the other way around. Marc also shares what happened when he took his concerns to federal regulators, the Department of Justice, and the New York Attorney General's office. The conversation covers how he wrote and self-published his first book in his 60s, the challenges of promoting it, and what everyday citizens can do to stay informed and speak up. It's one guest's perspective on oil markets, the financial crisis, and civic responsibility. Listen to the full episode, and subscribe for more conversations on thriving after 60.
