@ElwoodBlues Agreed! It appears though that @Confined is still peeking at you.
There are many causes for the results shown on thise charts. Foremost to me is nutrition: The poorer folk in the USA are not educated toward a good diet - Television tells them what they should eat and you don't see 'good foodstuffs' being advertised on TV. Secondly, the graph on expenditures may be skewed by the type of 'health-care costs' that are included: Money spent on 'beautification' (ornamental plastic surgery / spa treatments) or chiropractic, orthodontic and repetitive 'hypochrondial' treatments by rich people can move these cost statistics far to the right.
As for Universal Health Care being a 'disaster' just points to the ineffectiveness of how it is administered. It does not mean that the people who need it don't benefit from it.
@JollyRoger The US healthcare system for many years made it more difficult to get preventative care and to be reimbursed for preventative care. I think that's the biggest driver of our higher costs combined with lower life expectancies.
