I'm going to reiterate some of what Jkeb has said. First, a lot of jobs don't come with insurance. And when Obama and others were debating what the ACA might look like, one of their central concerns was the uniquely American tradition of relying on employers to provide insurance. One concern: that it makes American companies less competitive. And if you want to cite personal experience, I have known people who were not able to take new jobs because of pre-existing conditions (because the insurance provider would not cover them). There are good reasons why the pre-existing condition proviso is one of the most popular aspects of the ACA. Finally, with changes the ACA is sustainable. It works very well in some parts of the country. And who else would  carry the cost for anyone ill, with a pre-existing condition or not? Other people with insurance. Because that's what insurance is for - the spread risk around and minimize the cost for all. What would you do? Let them die?
