There is some public healthcare but no universal healthcare.
ER is not healthcare. You do not get treatment for chronic diseases, cancer etc. ER only treats you for the life or health threatening consequences of not getting treatment.
Folks suffer until things are an emergency as well and hospitals won't always help if you, say, need surgery for cancer that isn't presently killing you and isn't an emergency.
My wife's hospital was hit hard by ACA because it reduced federal funding for uncompensated care. The idea was that the funding could be cut because more people overall would be insured. Unfortunately enough of their patients still are without insurance that the funding shortage led to two rounds of layoffs. They seem to have adjusted to the new financial reality now and are hiring again. But the first couple years after ACA passed were tough.
I guess it would be more accurate to say that the federal government funds uninsured ER visits, but the funding falls short of what is necessary especially after ACA.
