While I'm sure there is some truth to this, you do run into the problem that people don't want to admit the mundane reasons they do things sometimes. People join armies all the time because they need a job, but if you ask I'm sure many of them will tell you it's due to a more personal reason or nationalistic pride. That's not confined to the military of course. It seems almost rude to admit you do your job to get a pay check in many occupations.
