> if your employer is paying for your family's healthcare

Isn't this true of every full-time job? But people quit and get new full-time jobs all the time.

Maybe in the US, but not in Europe. Health care and the education of your children is largely not dependent on your job. Shades of grey of course, I don't think university education is free in the UK anymore (it was when I was at university) and private health care does exist

Medical Feudalism is just how things work in the United States.
