Josephus,
I’ve paid for my health insurance my entire adult life. If you uncle didn’t have it, he was owed nothing.
I have paid taxes my entire adult life, we are not picking up the healthcare tab (or welfare) for the entire globe. Why do you feel that people like me should pay his bills?
Also, seems your uncle’s story is changing a lot.
One of the very first things my wife and I do when taking our family out of the country is check our health insurance coverage at our destinations. If there are problems, we change our itinerary. It’s simply a wise personal responsibility. Apparently common sense and self-reliance isn’t a characteristic of the Duncan’s.
