What about the Flying Spaghetti Health Care monster?

Note the median age increases until about 2035, but the big problem is that their will be a lot of elderly Boomers. Alzheimer's is expected to peak at around triple today's number. Then there's diabetes, metabolic syndrome, and a lot of nasty things that derive from those conditions.
The elderly by necessity use more resources per capita than a younger population.
Day care for Alzheimers patients runs $60 to $150 per day. Assisted living $1500-$4000 per month.
Medicare pays for 100 days of skilled nursing. That's it. By definition, UHC must pick up for those costs.
No you can make a moral argument for covering these people, but things are going to get cheaper?
Oh, looky here

I figure it's harder to deny the obvious with a link.
