Immigration needs to be reformed. That is a separate issue than health care, although of course they overlap.

Right now, anyone who shows up in an Emergency Room with no insurance gets treated anyway, as it should be, but the costs get swallowed by the rest of us with insurance. It doesn't matter WHY the person has no insurance - whether they are here illegally, too poor to get insurance, unemployed and coverage ran out, just didn't buy insurance - it's all lumped into one category. If the law works the way it should, everyone here legally should have some sot of insurance coverage, as there will be subsidies for extremely low income people, etc. But having insurance will hopefully mean they will go to the doctor for preventative care, and not end up in the Emergency Room at all. A minor asthma attack, for example, is far cheaper to handle with medication at home when necessary, than waiting until it has escalated into a life-threatening condition requiring immediate treatment and days of hospitalization. That's one example I can speak to from personal experience, as a lifelong asthmatic.

Don't ask me about any other medical conditions, that's the one I know.
