The usual reasons:

- wife has no job (due to move to Seattle), just had kids, need to pay for housing: unless you can get another job immediately (which is hard if you're too busy to interview), quitting will be a disaster

- boiling frog: it wasn't awful on day 1, so at some point he'd have to acknowledge that things have changed

- negative reinforcement and the cult: dysfunctional organisations are often good at making you think it's your fault. Hence the therapy.
