Why do lack of benefits bring emotional challenges to low wage jobs?

To answer this, think about what benefits people get as
part of their compensation at good jobs and then think about life without those things. 
The most important of these benefits are health insurance and sick
leave.

Imagine life without health insurance.  If you get
sick, you can't go to the doctor.  Much worse, if you are a parent and your child gets
sick, you can't bring him or her to the doctor.  I can't really imagine anything worse
than the idea that I would have to allow my child to suffer because I could not afford
to bring her to a doctor.

Similarly, imagine life without
sick leave.  If you get badly ill and have to miss two weeks of work, what happens to
you?  You get no pay and you may face really serious consequences like losing your
home.

Now, if you were in that situation, wouldn't you feel
emotional challenges?  I believe that you would.  I believe that people in such a
situation would feel constant stress because of the fear of having something happen that
would expose them to the consequences of not having health insurance or sick
leave.
