I was referring to the whole "Walt used to work at a company, and stuff happened" background, which the writers have completely abandoned and forgotten everything about. It made Walt's choice to not take the offered money really uninteresting, because he might have had reasons to that were barely alluded to in the show.

A guy presumable goes from working in a billion-dollar company to a K12 chemistry teacher, and we're somehow not supposed to try to understand the prior history, which to me is paramount to wrap our heads around Walt's thoughts and state of mind.
