Your comment already has a lot of responses but one thing I didn't see mentioned is about the tough physical labor. It is often neglected that working at the computer is really bad for your body. Sitting for hours is unhealthy and creates all kinds of problems: obesity, disc prolapse, bad circulation, so much more. Also your eyes suffer a lot and become worse much faster than in most other jobs.
I agree that being a SWE is certainly not the worst thing in the world but it has also a lot of bad properties that often are overlooked and the most positions do not have moon salaries, that we see on HN regularly.
Also to do whatever lower income job you don't need to study for 5+ years (master). You need to compare with jobs that have similar requirements to your education.
