What kind of rationing do we want?

...universal, unlimited insurance completely fixes things! Everyone will get all the medical care they want. No one will ever be denied or disappointed again!

But that's nuts. It's the same as claiming that rent control guarantees everyone affordable shelter or that the minimum wage guarantees everyone a decently paying job. To which from long, long history we discover that that might be correct, if you can find a vacant apartment or an available job. (Which is followed by liberals shrugging: hey, it's not our fault if you can't find an apartment or a job. It's the fault of greedy landlords and stupid employers. Besides, we meant well, so we're proud of ourselves, and that's all that really matters.)
