I just read a great article by Barney Blakeney about the working poor and their health.
Basically, Barney Blakeney points out that the actual health problem for the working poor is that they cannot afford to get sick and that they have to go to work even when they are sick because they cannot afford to not earn a paycheck.
I think he makes a great point.
Regarding health and the working poor, society has a problem far more extensive and deep-rooted than the lack of healthcare insurance. The working poor need to work more than they can to earn an incomplete income, and they cannot take time off to recover from illness. They must work through illness because they have bills to pay.
