Single-payer health care - Wikipedia
I do see some truth in the following statement about. This, I believe, is the core concern from the Conservative perspective.
“Once a large number of citizens get their health care from the state, it dramatically alters their attachment to government. Every time a tax cut is proposed, the guardians of the new medical-welfare state will argue that tax cuts would come at the expense of health care — an argument that would resonate with middle-class families entirely dependent on the government for access to doctors and hospitals.”
