Your link doesn't have any analysis on how preventive care is the cause of increased costs.
But there are lots of ways that are obviously not related to preventative care that drive up costs.
Our doctors and nurses make way more money than doctors and nurses in other countries.
We spend more money on questionable, or low yield procedures that have low returns that other countries don't.
Not to mention medicine just isn't that good at preventative care. The only real preventative medicine are diabetes medications and cardiovascular medications.
