What's the point?

Iisn't health insurance supposed to prevent you from this..... after all that's why they call it insurance.

They concluded that 62.1 percent of the bankruptcies (in 2007) were medically related because the individuals either had more than $5,000 (or 10 percent of their pretax income) in medical bills, mortgaged their home to pay for medical bills, or lost significant income due to an illness. On average, medically bankrupt families had $17,943 in out-of-pocket expenses, including $26,971 for those who lacked insurance and $17,749 who had insurance at some point.
