A bit of perspective: according to Gallup, as many as 85% of people worldwide hate their jobs,

although in the US it’s “only” 70%. So negatively about employment, any employment, is the norm.
And the “negativity” isn’t limited to physicians:

As pointed out above, there are objective reasons to not become a physician. It takes a long time to get through school, residency, etc, and medical school is extremely expensive and most offer little or no merit aid, so it’s all loans. And while in residency, it’s tough to put a dent in the debt as residents’ salaries are not very generous, so new docs are postponing repayment for years.
And what many seem to miss: as a physician, you’ll be dealing with sick people. This can be extremely challenging, as we can be difficult to deal with when sick, and we often want positive results immediately.
But since we also share anecdotes…well, those would indicated being a physician is rewarding. At Thanksgiving dinner, in addition to the rest of us(it’s a big family), we had six physicians, all in different specialties, three men, three women, two older four younger. All complained ceaseless about the work hours, insurance companies, etc. But when questioned directly, all said they couldn’t imagine doing anything but being a physician, and would be proud if any of their kids became physicians.
