Although its true that no job is permanent anymore, I still think permanent jobs still have more security than temporary ones. Employers often feel less guilty about letting go of a temp.

Also, permanent jobs have better benefits. The health insurance that temp agencies offer to temps are no good. I temped one time for 3 months for the same agency, and became eligible for the agencies "health insurance" plan for their temp workers. Well, I called around and found out that no doctors in my city anywhere, took this insurance. And I live in a big city. Most doctors offices had never even heard of it. It was pretty much a fake health insurance plan. I felt scammed. If I'd known what a scam their health insurance was, I would have worked harder to find a permanent job during that time.
