How do increasing numbers of uninsured Americans add to the health care costs?

To make a complicated story a little shorter:

When people are uninsured and have to use the hospital, they have to pay for it themselves. But these uninsured people usually do not have much money, so they can't afford to pay it.

If they don't pay, then it means the hospital lost the money that they should have gotten for that treatment (the doctors and nurses have to get paid, the equipment costs money, the drugs cost money, etc)- to make up for it, they then raise the prices on everything else.
