I am sure many people are aware of what happens when someone is out of work for a certain time span, it seems a little rude to be trolling about such a common misunderstanding though. Some people know and some do not, if you know and assume others do not, then take the time to educate them not bash them for it. Ignorance shows through that way many times over and its not very nice.
I know many people who have been out of their preferred work industry for years too, but they are still working in the best way they know how. If the job pays then they are doing it. I really get tired of seeing people who assume that just because one job is not available then no job is. Grow up and realize that even in a down economy you can not always get what you want, you get what you can.
