Comment by Bill at 10:17 AM:
I have a doctorate in chemistry, and about four years ago I lost my job due to cut backs. I have not been able to get back into chemistry. Those of us in science are not protected by unions like doctors, lawyers, and nurses. I think science is a great hobby, because there are not enough jobs for those of us that have the skills. If you are and older scientist or engineer then you are really in trouble if you lose your job. We really do not need people from other countries to come here and fill jobs.
