My brother is a surgeon. And before that, a doctor.
And yes he worked all the hours in the day and still does and always has.
He has never stopped studying - he has constantly studied his whole school and working life.
Being really good at something takes hard work.
And also it makes total sense that employers seek out those people for whom it's more than just a job - because those people tend to have a higher level of expertise. You might not like that but the logic is reasonable.
