The thing is, plenty of illegal immigrants are normal working people, paying taxes, stimulating the economy, etc. To demand citizenship papers before receiving health care defeats the purpose of universal coverage. The general populace is not well served having an underclass of sick people spreading disease due to lack of access to care. We will care for these people regardless of their status when the show up in ERs, we’re all better off when care can be provided before that’s necessary. Immigration needs reform, but that’s going to take a lot more than a wall on the border.
