When it comes to moving, the non-aviation world is not much better. I know a guy who moved out West because he got a great job offer. He moved out there, got the job and went to work. Within a month or so they had gotten what they wanted out of him, and laid him off, told him they did not need his services anymore. So he is stuck in California, he has no job, little money, no family there, no contacts, nothing.
It happens in all industries, especially in competitive fields, and even more so when you are just starting out at the bottom.
