If you put as much effort into law as you have into software you would be a good lawyer and a terrible developer. It is a choice. Today your effort learning software pays better (with exceptions both ways) then law, but historically law has been good. I decline to speculate on if law will earn better than software in the future.

You can say the same for medicine, any other engineering field, farming, ditch digging, or any other job. Regardless of which you choose some love it and some it is just a job.
