“...Insurance is private sector socialism...”
No, it’s not. With insurance, you pay, and you get covered. With socialism, you pay, and don’t get covered, and someone else doesn’t pay and does get covered.
Insurance is risk mitigation. All insurance schemes, private or public (e.g., unemployment “insurance”) are liable to moral hazard, that is people become careless or take risk because they have insurance. If health insurance did not cover skiing accidents, there would be a whole lot less skiing, even if “ski coverage” was available, because it would be expensive.
