What is the most under appreciated career and why?

Lab techs make about medium income and are very low stress. The kind of job that if you go on vacation for a week you dont come back to a weeks worth of work waiting for you.

An associate degree is usually all you need. Kind of an overlooked career for people wanting to coast through life. It also looks good on paper and can lead to inspector jobs.

This is for food science, I cant speak for bio labs.
