It is a well established fact by the CBO (Congressional Budget Office) that roughly 10% of the medicare budget is wasted on fraudulent claims (even though their rejection claim rate is roughly 1000 times that of most private insurance).
So there are some cases where the status quo is untenable, fraud is blatantly obvious, and people could die untreated do to a lack or resources.
Yes, fraud and corruption should always make the headlines and should always be a priority to eradicate.
[EDIT for typo of medicaid instead of medicare]
