Based on his positions and votes throughout his career, many commentators consider his political platform based on tax-funded social benefits and not on social ownership of the means of production. Some have described Sanders's political philosophy as "welfarism" or "social democracy" but not "democratic socialism" defined as "an attempt to create a property-free, socialist society." Some members of various U.S. socialist parties and organizations have said that Sanders is a reformer of capitalism, not a socialist. Others distinguish among "socialism", "social democracy", and "democratic socialism", and describe his philosophy as extending from such existing liberal programs in the U.S. as Social Security and Medicare, and more consistent with the social democracy found in much of Europe, especially the Nordic countries. Noam Chomsky and Thomas Frank have described Sanders as "a New Dealer." Other observers, such as Lane Kenworthy and Bhaskar Sunkara, suggest that his views are more closely related to those of social democrats.
