This was already addressed in the original post. Why write in this "spelling it out for you" style when they already addressed it?

This is really reductive. There are multiple reasons:
- very stable employment
- very prestigious job, and has been for centuries. Conveys authority. Your family can boast that you're a doctor.
- very interesting tales come out of employment, and your family probably
- very easy to feel good about being a doctor - directly helping people etc
Not all of those for everyone, and they no doubt don't all turn out to be the case, but doctors apply for multiple reasons, and many of them aren't in high-paying areas at all. Doctors (in America, which I assume is what you're focusing in on) are paid well partly because they have high expenses in terms of liability insurance.
