Dude, you've cherry-picked. The numbers say US quality is average- lower even than New Zealand that spends well under half as much, but still manages universal coverage. US cost is higher if you consider only those with access.
In your shoes I'd be asking why costs keep rising when you already spend too much. There's a money leak somewhere. It's not the doctors and nurses, so where is it?
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
