[Healthcare] is virtually the only part of the economy where I can go out and get any service I want—cancer treatment, open heart surgery, have a wart removed, whatever it is—and I pay $3 for it or $5 for it or nothing, even if it costs $50,000 or $100,000. I mean, imagine if you had the same situation with automobiles. Where I could show up at the car dealership and I could say, ‘I want the Mercedes for free.’ Well, people say, ‘You can’t have the Mercedes for free. You have to pay $50,000 for it.’ You say, ‘Why not, I have an inalienable right to free healthcare. Right? Why don’t I have an inalienable right to a free Mercedes?’
