Final answer:
James Morone suggests that the main reason behind the lack of national health insurance in the U.S. is due to its private healthcare system and ideological differences regarding social welfare and individual responsibility.
Step-by-step explanation:
According to James Morone, the major reason that the United States is the only industrial democracy without national health insurance is heavily tied to its unique healthcare system structure and societal attitudes. In the U.S., healthcare is primarily paid for and provided by private firms, in sharp contrast to the government-managed healthcare models seen in other industrialized nations. While the U.S. system has the capability of delivering high-quality care and medical innovations, it faces challenges in controlling costs and ensuring access to basic medical care for all citizens. Another factor includes ideological differences, with some Americans critiquing the extensive welfare benefits prevalent in Europe as destructive to personal responsibility. Indeed, the debate on the role of government in providing healthcare reveals underlying values and opinions regarding social welfare and individual responsibility.
