This paper answers the title question, “Yes,” on both counts. The first part of the paper argues that modern liberals are socialists, and the second part argues that they are also social democrats. The main idea behind the first argument is that the state has effectively taken control of the incidents of ownership through its taxation, spending, and regulatory policies. The main idea behind the second argument is that the institutions of social democracy are replicated by the institutions favored by (...) modern American liberalism. Specifically, the takeover of the American healthcare system, Social Security, employers' mandatory contributions to unemployment insurance, and workers' compensation insurance replicate the institutions of social democracy.
