Conservatives and liberals both advance statism, but if anything goes wrong, they blame libertarians. From Ron Paul at ronpaulinstitute.org:
Recently several prominent social and populist conservatives have attacked libertarianism. These conservatives, some of whom are allies in the fight against our hyper-interventionist foreign policy, blame libertarianism for a variety of social and economic ills. The conservative attack on libertarianism — like the attack on the freedom philosophy launched by leftists — is rooted in factual, economic, and philosophical errors.
Libertarianism’s right-wing critics claim libertarianism is the dominant ideology of the Republican establishment. This is an odd claim since the Republican leadership embraces anti-libertarian policies like endless wars, restrictions on civil liberties, government interference in our personal lives, and massive spending increases on welfare as well as warfare.
Anti-libertarian conservatives confuse libertarianism with the authoritarian “neoliberalism” embraced by both major parties. This confusion may be why these conservatives blame libertarians for the American middle class’s eroding standard of living. Conservatives are correct to be concerned about the economic challenges facing the average American, but they are mistaken to place the blame on the free market.
The American people are not suffering from an excess of free markets. They suffer from an excess of taxes, regulations, and, especially, fiat money. Therefore, populist conservatives should join libertarians in seeking to eliminate federal regulations, repeal the 16th Amendment, and restore a free-market monetary system.
Instead of fighting to end the welfare-regulatory system that benefits economic and political elites at the expense of average Americans, populist conservatives are promoting increased economic interventionism. For example, many populist conservatives support increased infrastructure spending and tariffs and other forms of protectionism.
