WaPo continues to print fake news about Medicare for All

This article pointed out an error, which was subsequently corrected. But then the Washington Post keeps repeating the lie that they earlier corrected. Why is that I wonder? What is their stake in perpetuating this lie? The lie was that Medicare for All would reduce doctor payments by 40%, a broad and inclusive statement. The fact is that it would do so only for private insurance rates.

"This is because only 56 percent of Americans have private insurance. So while private insurance patients would see their payments reduced by 40 percent, Medicare patients would not see their payments reduced at all, and Medicaid and uninsured patients would actually see their payments increase."
