Could be okay, although 'working' might be a term you should reserve for the super-rich, many of whom get that way working insane hours. Bill Gates lost a girlfriend because of his "7-hour-turnaround" rule: he had to be back in the office within seven hours of leaving, every day. I'm not sure many people in your version of the working class have that issue. Perhaps the "working but not saving class" would be more appropriate.
