Have you ever noticed that libertarian and liberal both begin with the same five letters? Is it a coincidence, or not?
There are indeed folks who have begun to call themselves 'liberaltarians'. It is as though libertarians are seeing the light.
Somewhat, anyway. The precise nature of the change in heart isn't really important. The fact is that libertarians are a bit of a schizophrenic bunch: liberal on social issues while conservative on fiscal matters. It is fair to ask if you can have it both ways and maintain any philosophic consistency.
Can one really be fiscally responsible in public policy while essentially arguing that social responsibility is a radically different question? Why do we have the freedom to do almost anything we want personally (provided it does not violate that vague and rather self-serving platitude: so long as it doesn't harm anyone else) yet have no such similar freedom if you're a bureaucrat or politician to do what you personally want done? Indeed, how can one reasonably argue that financial discipline and personal discipline do not go hand in hand? If you are no good at the one it is doubtful you can be particularly effective at the other.
In short, libertarians are essentially liberals who happen to like fiscal discipline. Yet such is like getting blood from the proverbial turnip. If folks are not personally disciplined they are not likely to be publicly disciplined. After all, we reap what we sow. Sow freedom, reap freedom, with all the errors that must grow from that field. But sow justice, the idea that some things are really right and others really wrong on their own merit, and we improve society by having bettered ourselves.
