Under deadline scheduling, every pending job _eventually_ has highest priority as time elapses. (Assuming new jobs can’t arrive with deadlines in the past.) Every job is eventually serviced.
The “pain” experienced in an overload situations is spread among all late jobs. Contrast this with fixed-priority scheduling, where lowest priority jobs will be starved completely, until the overload is resolved.
