I live in Texas and currently pay $780/month for health insurance through my employer. Over 1/4 of the people in the state have no health insurance at all. So no, that number isn't very high.
You must have had lots of health problems in the past or your are lying about that number.
I'm insuring a family (wife & child) as well as myself which drives up the cost. If I were to leave them uninsured then I would pay $0 out of pocket.
