Oh, but it gets worse. It's bad enough that the government is being bilked for hundreds of thousands of dollars on behalf of those without the ability to pay, but even for those with significant assets, there are "perfectly legal" tax dodges that can be set up for $XX,XXX so that Medicaid pays the $XXX,XXX bills while the family inherits the $X,XXX,XXX estate. And if you pay the lawyers a little more, they can probably even figure out how to avoid paying capital gains on the distributed assets if they are below $10 million.
I don't see much hope for the insurance reform in the US until we can get end-of-life costs under control. I don't if "Ponzi" is quite the right term, but it's definitely a system rife with fraud.
More generally, "House of God" is a stunning inside look on how the US medical system actual works: http://slatestarcodex.com/2016/11/10/book-review-house-of-go...
