He took a ~25% paycut, he works harder and longer than he did before (as a chef, mind you, regularly known for 100+ hour weeks), spends close to half of that time driving, and often sleeps in the office. He went from probably being a few years away from running his own three star restaurant to running an unsalable, shrinking business, owns 400k worth of similarly unsalable equipment, in a slowly dwindling industry (dry cleaning).
His marriage has fallen apart (did I mention he moved 3 hours away from his wife + children to run the business), his mental health seems atrocious, and the only thing the future seems to hold for him is a piece of a slowly shrinking pie.
His father built a burgeoning postwar business that gave his family a good life, but markets change, and businesses that once made sense no longer do.
