If us folk shot in head without VIP insurance like Congressman Giffords would we survive?

She had all this fancy surgery by top neurologists where they removed part of her skull to prevent death from brain swelling, she's in a medically induced coma etc that all the politicians insurance covers. I know my benefits wouldve capped out and my family would be looking for a casket. Did the shooter have legitimacy in his gripe (not in his shooting)?
