Why not free universal health care?

Reading responses to an article on the Christianity Today web site I came across a lady who asked, "Why not free universal healthcare?" Her question reminded me of children who ask simple questions such as "Why is the sun hot?" If you give them the physics of how the sun works, they don't understand it. So I tell them God made it hot to keep us warm. Of course, then they ask, "Why?"

I gave the woman a brief response from economics and she responded that her Canadian friends were happy with their system so there was no reason for the US not to have something similar. Of course, if we limit our knowledge to just what the woman's friends in Canada say about their system then without a doubt we should rush to the ballot box and vote for the most socialist Democrat candidates we can find. The problem with her logic is that she assumes her personal experience and those of her Canadian friends are all she needs to solve the problem of healthcare.
