Is a Masters in Forensic Science worth it financially or in the job market? Which Masters degree in biological science is better financially?

Maybe one that could be used as a prerequisite for a credential in health care?

Practically any role in health care requires a state license or some proof of qualification that serve as credentials. While health care may not be on your list of things you want to do with your life it's an industry with a constant need for service providers, and maybe not a bad place to be while waiting for a dream job opportunity.

Our kids are architects and entered the job markets during economic slumps but found jobs in related businesses but not where they wanted to be. It took a few side steps over a few years to eventually slide into the ground level of what they really wanted.

...pharmacologist maybe. Unless you're cutting into someone or doing dev for bad drug companies, moneys pretty much all bad in healthcare.

I think forensic science could be quite good. Analyzing failures of materials, processes, equipment, vehicles, etc is exciting and should pay well. I did architectural analysts of computer chips, solutions, and software. Paid pretty well and not as detailed or specialized as the job you're looking at.

You do either because you love science although I would imagine that forensic science would get you a job in the CSI
lab.

Which one are you passionate about?

Idk id think pdychology.
