So, after reading the one link above and scanning a couple of others my opinion is the same. As a nation we can't even agree on the necessity of the fairly simple fixes needed to make health care affordable and available to all, even with numerous other national models available from which to draw ideas.

Fixing this systemic problem is critically important to citizen welfare and relatively simple in comparison to a total reworking of our monetary system, and yet even incremental changes like the ACA are hugely difficult and hugely divisive.

A fundamental alteration of the monetary system is many orders of magnitude more complex and of course would be bitterly opposed on political, ideological, and practical levels.

As I said at first, those proposing ideologically driven and fundamental changes to complex systems that have evolved over decades need to explain how that change gets made;)
