Strength
Some people seem to think working is a sign of strength. It doesn't take strength to go to work and make money, you're going to do that anyway to live. You could be the one that weighs 98 pounds soaking wet and hold a job for years if it's what you had to do to live.
The guy/girl thought it took strength to go to work and pay the bills. Really there were strong people who were unemployed and weak people who still had jobs simply because strength is not a factor in who works and who does not.
