It's underfunded, but it remains one of the top healthcare systems despite that, and provides universal care.

It's however relevant here to illustrate how insane the US healthcare situation is, in that Americans pay enough in taxes towards healthcare to provide universal healthcare if structured better, but chooses not to.

As an example of how to provide cost effective universal care, the NHS is a shining beacon. If the UK spent comparable amounts per capita to comparably wealthy countries to upgrade it, it'd be 20-30% more expensive, and a lot better, and still vastly cheaper than US healthcare overall.
