Really? This is a modern problem? Please, cite a source where this issue has invited the Feds into the field in the last few decades.
It's not been an issue in the "last few decades" but I read somewhere that it was an issue when Medicare/Medicaid was originally being discussed. Think pre-60's.
It was also an issue in Colonial America at the state level. State judges spend a lot of their time forcing communities to carry their fair share of the indigent care. I read that researching the history of poor laws in America.
