I think if you make about 350k you are in the top 1%, i.e. the hated one percenters. Can you do that in Anestheisa your first year out. Yes, you will work hard, like 60 hours/ week, but it can be done. I think the median salary in this country is about 50k, so your first year out you can make 7x that of the median salary in this country. Of course, you will be 30 years of age. But basically it is a stable job.
Nothing is set in stone. Things change. I have friends older than me who are partners who work half as much as me and earn twice as much. It is just how the ball falls. I just worry about one day at a time.
Things change. There was a time in the 90s where there were no anesthesia jobs from what I've been told by my elders. Then in the 2000s, I heard of starting bonuses in the six figures. In fact, I got a bonus when I started a few years ago. Now the number of jobs on gaswork is about 1/3 than when I started.
