> if a company is shutting down, it obviously can't provide severance
Not really true. The company is owned by its shareholders, and they may choose to use funds belonging to the company (after paying outstanding obligations) to pay severance, or they may divide the funds among themselves. If there are no funds, they can choose to invest more to pay severance. Obviously they're unlikely to want to do that, but it's not a case of "can't" but rather "won't".
