A person who habitually chooses expedience (convenience and advantage) over principle; someone who favors practical short-term gains over moral considerations.
Formed from 'expedient' plus the suffix -ist (meaning 'a person who practices or believes in'). This is a critical term used to describe unprincipled decision-makers.
Calling someone an 'expedientist' is a sophisticated insult—it's what you call politicians and business leaders who always choose whatever gets them ahead fastest, consequences be damned.
