Because our dad was paid for every hour of work he put in. He invested his time by the hour and his risk was minimal. For a startup coder he or she is investing by the month or year, and to walk away from that with not much to show for it can be awful.
These coders arent paid extra for all nighters, they aren't compensated for losing relationships, they aren't covered when they burnout, all for a realistically very slim chance of striking it rich.
