My wife is a doctor (GP, before internal medicine in biggest hospitals), experience with France and Switzerland. What you say is true - they all start as naive optimists who get treated brutally by whole healthcare system first 7-10 years after school, everybody knows it, often illegal from hospitals but good luck suing your employer. Burned out, 60-70 hour work weeks with weekends is the standard, night shifts, a lot of responsibility with little help/oversight. Always 1 oversight away from harming/killing somebody. Many in Switzerland that are Swiss dropped out, foreigners don't have it so easy.
Then afterwards they are put into position where they have 30 minutes for patients (in France its ridiculous 15 mins, saving money = worse diagnosis/treatment, no way around it). Don't expect miracles if they see 20 folks like you daily, ideally with very vague problems like chest pain which can be anything from sprained muscle due to bad sleeping position last night to heart attack, while having 10 other comorbidities and taking various medication.
Doctors behave as whole system forces them to behave.
