If you just think about health care it doesn't make sense. Nice succinct article about the broader picture that explains it quite well. I would add, how do you expect the many to embrace the moral principle of the stronger helping the weaker when every day they ignore and drive by homeless veterans and others, who die from lack of care every week or two in major population centres, even San Francisco which is so liberal? It also explains how it becomes acceptable for Republican congress reps to use the phrase "those who have earned their health care" referring to those who have coverage in speeches. I presume they are devout Calvinists who feel babies born into covered families are among God's deserving elect.
It is like developing countries with a gated elite that has a strong sense of privilege, but in some ways far more reprehensible, in that the poor minority is so small and the excess wealth to correct it completely is clearly present.
