I have a similar impression; and based on the people I've met, it's somewhat accurate. People with higher education in CS I know tend to go more towards full stack or back end work, while web front end devs often are career changers. The entry barrier for web technologies is just rather low. This is probably the main reason for Node's huge growth in the past years: It's just the path of least resistance to get into back end development.
