This is socialized medicine. The parents CAN pay, and WILL pay. The money has been donated. Nothing is burdened on the tax payers. But, liberals don't want the Gard's to spend that money on their son. They want it spent on someone else. Someone THEY deem would benefit more from someone else's money.
The problem isn't with Charlie Gard. The problem is really with the researchers and medical developers that come up with the experimental treatment in the first place. If ONLY they woujldn't waste their time (and all that money) looking for treatment and cures for rare diseases. Just think of the money available for the third world needy.
Now that the wrong has been done, and some team came up with an experimental treatment it is necessary to have someone with the disease to treat, just so, you know, to see how close they are to it working. Charlie Gard is going to die. But maybe what is learned from his treatment could help the next Charlie Gard. Now, if that's where your problem is, they the Gard baby has nothing to do with it. You don't want the line of inquiry in the first place.
