During Part One of this series, I approached the end of my post with this paragraph.
Apart from the political opposition from the insurance companies that Medicare for All would have engendered, I think the main justification for abandoning Medicare for All and switching to the PO and eventually the PO-less ACA, was actually neoliberalism. The President, his main advisers, the Democratic leaders in Congress, and most progressives working for Washington progressive organizations were steeped in neoliberal doctrine. They viewed the Bush tax cuts and the two Wars as unpaid for. The ARRA stimulus Act was similarly unpaid for and added to deficit spending and to the debt-subject-to-the-limit. They believed and most believe today that the Federal Government can have solvency problems if the debt-to-GDP ratio increases too much, and interest rates on the national debt are driven up by the bond vigilantes.
