According to Barr, the solution to the today's problems "is less government," reflecting his view that government is often the problem rather than the solution. Barr feels that "private charity should be the first resort for anyone in need," rather than the government. To that end, "government should eliminate regulatory barriers that inhibit private philanthropy and expand tax deductions to encourage charitable giving." He would also seek to cut federal spending in "every area." In an entry on the Huffington Post, Barr called the War on Drugs a "failure" and suggested that states should determine their own drug policies. Moreover, as President, he would attempt to reduce the "most destructive impact of drug prohibition," namely, "the human and economic costs of imprisoning so many thousands of people for drug possession." In Barr's estimation, the government "should stop attempting to 'manage' the free market," as he puts it in his campaign platform. Its legitimate functions are only to "protect property rights, adjudicate disputes, and provide a legal framework in which voluntary trade is protected." As a corollary to this, Barr emphasizes that government spending "can and should be cut." He additionally sees dramatic alterations to the tax system as necessary: the corporate income tax, estate tax, and capital gains tax all "must be reduced and eventually eliminated." America, as Barr puts it, "should not be the world's policeman." Instead, military expenditures should be focused on national defense. In attempting to preserve peace, the most effective route "is through an expanding free market, backed by a full range of cultural and other private relationships." He would withdraw American soldiers from Iraq "without undue delay."
