Many people really don't connect the dots between tax policies and health care insurance/payment policies. Saying that health care/insurance is "free" makes it difficult to have a coherent policy discussion.

I know the ship has sailed on this but it I continue to see people truly believe that they are not paying for health care and that sort of misguided understanding of economics shouldn't be encouraged as it makes it difficult to have coherent discussions about many different public policies.

    College education should be free...
    College loans should be free (even when they weren't when the loan was taken out)...
    Income should be free (UBI schemes)...

If you switch to "subsidized" from "free" the list expands exponentially.
