Two parts.. First, he freely chose the situation he is in, why should the government regulate consequences of choices you make? Second, no one is denied health care in our system, that is a common myth. Emergency services can never be denied and the very poor do have Medicaid. When you are talking about universal healthcare, you are not talking about the poorest of the poor losing emergency services. If the market where truly free, your friend could freely choose the plan that best serves him, just like food. If a person needs food, they can choose cheap fish and chips, or they can, if they can afford it, choose to go to one of Ramsey's places. If the market where free, you would have companies offer services to all potential customer bases. In a universal system, even the poor person has to pay a chunk of the rich person's visiting Ramesey's place (using the food analogy.) Why should the poor have to subsidize the middle class and rich?
I think Europeans misunderstand our system. They are fed lies about our system.
“he freely chose the situation he is in”
What if he can’t get promotion? Then he doesn’t deserve a doctor because he is incapable of promotion?
As I said, taxes are staggered so the poor don’t subsidise much.
