Why are Computer Vision salaries so much lower than Machine Learning?

Looking at salary numbers online, a CV scientist salary can be roughly 15% - 30% lower than ML scientist salaries. What explains this (more specifically than supply/demand)? Thanks!

I remember Jeff Hawkins said in an interview that CV has less money in it than most people think.
