Bruce Bartlett analyzes Liberaltarians:
I believe there should be more balance in the libertarian strategy, with civil liberties and non-interventionism having closer to equal weight with economic freedom.
In return, liberals can learn something important about economics from libertarians. Liberals often turn to government to solve social problems simply because that is their default position. But often, there are private-sector alternatives that may in fact be superior. The rich diversity of America's states and localities shows there are many different ways of dealing with social problems that don't necessarily require more government.
I hope the dialogue continues.
Ezra Klein chips in his own two cents.
