This isn't just a US thing. For example, even though healthcare is nominally free at the point of use here in the UK, that doesn't cover long-term care for the elderly - you will have to pay privately for that out of your wealth to companies of varying degress of sleaziness until you have no more left, at which point the government will hopefully consider picking up the bill. Our current conservative goverment is planning on capping this and it seems fairly controversial.
