The issue in America is essentially that the system is paid by piecework. So the entire system optimises for the number of tests/procedures/operations etc. that can be performed. And that might not be so bad in and of itself, if 21st century medicine was reliable. But it's not, and the sad truth of the US system is that many of the (very expensive) procedures it performs have worst outcomes than leaving the patient alone.
In the Netherlands, a patient should not expect from a doctor to conduct any tests at all. I had no experience with the Dutch healthcare myself, but I've heard horrendous stories about it, for example how Irish expat went to a doctor with a problem of pain while swallowing, received nothing more than an advice "well, swallow less, then" (like in a bad joke about doctors), went home to Ireland a got diagnosed with a throat cancer there.
