The town I live in was a booming manufacturing town when i was younger. Our factories started relocating or shutting down 25 years ago. My dad had worked 2 jobs all his life. It was a good thing he had the second job because he was over 50 when he lost his primary employment. It didn't matter that he was a dedicated and responsible employee all those years, he and the others over 50 couldn't find jobs. My dad worked his part-time job until he died suddenly at 72.
A few years ago I was a temporary worker for Div of Workforce Dev. Nothing has changed, the people over 50 who had worked at a large local factory couldn't find other jobs even after going back to school on the taxpayers' dime. Employers prefer younger workers.
