Medical Bills Cause of Bankruptcies
That one popped right of Google, almost no effort required.
I personally can vouch for it. My Dad left behind a house worth <$10,000, about $20,000 or less in life insurance, and almost nothing past that. He spent most of his life without health insurance (pre-existing conditions) and only acquired it at the end when Mom got it through her work as a cashier (thank god). The pre-insurance Medical bills at the end would have not only bankrupted my Mom, but would have emptied out my life savings (about 3 months of income for my wife and myself).
Its gotten ridiculous out there. Dying is quickly becoming the single biggest expense for a family.
