Yes. I work in investment banking and have a salaried position and always have, except during high school. If it was taking me 60 hours per week to get my work done it would be a performance issue. I understand the concept of an associate at a law firm, or an analyst with a job in banking or a corporate job, working many many hours is standard. But once you start moving up the hours expected are reduced. It sounds like the OP was pretty much working two jobs and only being recognized for one job.
It was never my observation in academia, medical research/veterinary care - or even retail management - that ‘moving up’ reduced anyone’s hours.
Many jobs aren’t predictable as to how long things take. There are always crises, sudden staffing issues, fires to put out. However, generally jobs that carry greater responsibility do pay accordingly and confer a higher ‘status’.
Everything in life is a trade-off of one kind or another.
