Negotiate? Just quit. At some point you're better off doing literally anything else with your limited time on this earth. Way too much time and effort for too little reward. Who's looking forward to doing a decade of hard training only to end up with some 9-5 job and salary? That's just absolute nonsense.
Becoming a doctor is quite simply a stupid decision if you're not gonna get rich off it. You're replying to a citizen of a country which implemented your idea and then some. Believe it when I say the "get into medical school and you're set for life" meme has worn off.
You haven't seen the damage that stupid indebted underpaid doctors are capable of causing. I'm actually afraid of getting sick. Killing patients? I've seen worse.
