True, but people who stick around tend to be a little more willing to pay, even if it takes them time to do so. My doctor and I have a lot of talks around the subject of the current medical system and the stories she's told me about the changes are scary. And according to her, at least in this area, the illegals abuse it more than the legals. Its why her office requires insurance or payment in full up front. And, she doesn't milk people, if she knows a patient is having a rough financial time she works with them, if they have a history with the office.
Maybe its not a problem there in Colorado, but illegals are a big issue here. One good side effect of the recession around these parts is you don't see nearly as many of them loitering around the Home Depots and convenience stores --- I suspect many have given up and gone back.
