There is a pervasive myth generated by conservatives that the private sector is more efficient and less bureaucratic than government. This is perpetuated by those seeking to continue the "free market" in U. S. health care, which simultaneously exploits public programs through privatization of Medicare and Medicaid.
While it is tempting to look at just one metric--the decline in numbers of the uninsured, this is a trap if used to deceive ourselves as to the success of the ACA. As the above examples indicate, we still have a long way to go before we can say that we have reformed U. S. health care in the public interest.
You might think that we learned the lesson of discredited managed care in the 1990s. The term "managed care" is confusing to many, but really amounts to managed reimbursement rather than managed care, whereby a set prospective annual payment is made by federal/state governments, as in the case of Medicaid managed care (MMC), to cover whatever services patients will receive over the coming year.
