The economic meltdown serves as a backdrop for the characters' own personal struggles. We see Brad (played by Adam Pally) grappling with the pressures of adulthood, as he tries to navigate a complicated relationship and a stagnant career. Meanwhile, Kristen (played by Julia Louis-Dreyfus) is forced to confront her own sense of entitlement, as she's faced with the reality of her privileged upbringing.
