I'm going to suggest that you stay where you're at, if you really need the money. It's not just your field of work, It's across all fields, especially technical. I know too many folks out of work, that really need the money.
I am in IT and retired 2 years ago (to leave the bullshit), but I had planned on it for over 20 years. I did have some intentions of working at home part time, but the bottom fell out of this also especially after 9/11.
After 2 years, I could not go back as I have gotten used to this lifestyle and thankfully I don't have to.
A lot of these technical jobs are being exported overseas, and I don't think they are coming back. I believe that the U.S. is becoming more like the rest of the world - rather than the world becoming like America. Lots of poor folks. A very few wealthy and a shrinking middle class
