" Illegal immigrants inundate [NJ] hospitals"

From this:

New Jersey's escalating population of illegal immigrants is placing an ever-growing burden on the state's hospitals, which expect to lose $200 million this year on care to the underground community.

Doctors and administrators around the state are complaining that the cost of treating illegal immigrants has forced them to delay the purchase of life-saving technology or the addition of valuable staff...


What's the reason again the cost of health insurance is so high and seems to increase more each year?

And why the growth in "outsourcing"?
