I Had an Interesting Conversation

I had an interesting conversation about jobs, salaries, and health insurance.  The contention is that people choose those jobs with the lower salaries and no benefits.  I was reminded of the scene in the movie Caddyshack where the one caddy is trying to get a scholarship from the judge and he says well the world needs ditch diggers.  I guess that I question how many people self selected these jobs and what happens if no one self selects one of these jobs?  We would have no people serving us will that be ok?
