If it's rhetorical, then I'll just say 'yes'.  

Lot's of people that previously did not have health care are now making appointments to treat ongoing problems that they previously could not address.     Statistically, those people might look like they are sicker, they go from no treatment, to treatment on paper, but it's just treating what was a hidden health issue.   

It's hard to know savings when it comes in the form of something not happening.   How would we put $'s on not being sick?

Both sickness and health measure have many factors Mr. Sanders, very few could be measured solely by the medical delivery system.

Good question.   I think we should be focused on health care and affordability, not the method of paying for outrageous cost charged by medical providers.      The only measure that's getting attention is breadth of insurance coverage, (how many) and that has a high cost.    We should know why/how that cost is justified.
