Is actually due to Labor Supply vs. Labor Demand. I can envision a world where majority of jobs are all replaced by machines (from Baristas to Accountants), and web/software development (among other fields, such as specialized medicine) are some of the last places for people to remain self-sufficient off their own labor. With this over-abundance of supply, employers are capable of being extremely discretionary over their hires, and are able to pay just enough for their human capital to sustain themselves.
