In the US, elderly people have Medicare, so why is this happening?
I vouched for your comment, because I'm also curious. What healthcare costs is Medicare not covering?
I think you generally pay about $1k-$2k per year in premiums in total for all parts. There are also deductibles and copays. For example, the deductible is about $1500 for hospital stays and copays for doctors visits is 20% of the medicare approved costs.
So it's lower than private insurance, but not negligible. It can get pretty expensive if you require lots of procedures or medications, as many people do at that age.
Here is an article claiming the average cost for A and B parts is almost $8k per year.
