I absolutely believe what your ex colleague says/thinks of his job is exactly what he means, however he's comparing it with a retail job,which,in most cases are pretty crap. I also understand that even if the job may look crap, it can still be a huge improvement for the person who's doing the job. I've done enough crappy and good jobs in my life to know the difference, but I appreciate not everyone would have such a perspective.
