There may be a more fundamental problem with reforming conservative ideas. Over the last few decades, the definition of “conservative” has hardened into dogma. “Less government” -- deregulation, lower taxes and privatization -- is “conservative.” Any policy that doesn't include cutting government is “liberal.”
But there are a lot more ways to use government than not to use it, so the universe of “conservative” policy is therefore much smaller than the set of “liberal” ones. There are a million and one interventions, but there’s only one free market.
