Aa1, rav Moshe writes in a teshuva that not only is there no mitzvah at all in being a doctor, the motivation for those who do is almost entirely because of money. And he had a son in law who was a doctor.
It’s only the maskilim who praised doctors as some sort of angels, because they believed that they have the independent power to heal people. Maaminim believe that they’re merely shluchim.
