I am completely in favor of ACA and would like it to be expanded to Medicare for all. Most of my nursing experience was in ER and ICU. In both areas I saw the outcome for patients who were unable to get adequate primary care, especially for chronic illnesses. Two disease processes...diabetes and hypertension...come immediately to mind. Neither of these can be handled adequately through ER visits. Primarily, because the visits are precipitated by necessity of complications. It is too late for someone in kidney failure secondary to diabetes, or a stroke secondary to uncontrolled hypertension to be fit and healthy again. There are many life changing complications from failure to adequately treat chronic illnesses...blindness, amputations, pain, failure to heal or recover from minor illnesses or injuries, oxygen dependence, exercise intolerance. Complications from untreated acute illnesses or injuries are even more varied and frequently involve young, previously healthy folks.
From my experiences, I cannot understand why ANYONE can argue against some form of universal health care.
