Well, the transition from factory to elsewhere is a bit tricky, so if tutoring is an acceptable option for you, I’d advocate that.  Investment analysis is brainwork, and so tutoring exercises that particular muscle.  It also requires a bit of entrepreneurship, which financial people generally like.
The real worry with factory work is that it will suck you in and suck the life out of you and you will never be able to break out of it.  It will mark you and many people will (quite possibly unfairly) judge you based on it.  However, if you do break out of it, many people wil interpret that as a statement of your force of will too (like the bus driver CEO).
It’s a tough choice, and I don’t envy you.  Those are just my thoughts.  Personally, I’d be most concerned about how the factory job affects my available time and energy to pursue something better.  A short stint at something because you need to pay the rent is not a huge issue.
