Yeah. There's a finite amount of resources and a literally never ending avalanche of patients. At some point they're going to have to make a cold calculation.

I don't really know how it works in the US but here in Brazil it's actually pretty easy to order laboratory tests and imaging studies. There's taxpayer funded public health care but it can't handle the demands of the entire population so people would rather pay for the ultrasound or CT scan than wait two years for the government to provide it. An ultrasound costs about $30, an MRI costs about $150 and the price of a CT scan is somewhere between those two.
