Band on the Run is right about certain skills (such as knowing the French language) not qualifying one for gainful employment. I went back to college in my mid 30's, thanks to my second husband. His philosophy was that education was about "living with yourself," not just employment. I had been a top student in French in high school and wanted to pursue a degree in it.
What finally saved me career-wise was getting a government job. I came to Nevada and got a municipal job, first as a legal secretary, then as a human resources/hiring assistant, and, finally as a records librarian for the Building Department (my favorite and best paying job of all). Having the education can help you to score high on civil service tests. Tests are not weighted as much as they used to be in selection of employees, except for the federal government. A high score on a test can get you inside the door, but it won't keep you there.
Because I have a pension now, I am 'way better off that I would be with Social Security alone. Now I am learning court reporting, as there is a dire shortage of people with this skill, and I'm told there is little to no age discrimination because what really counts is skill.
