The Medicare trust fund, like the social security trust fund, is an accounting fiction.
There is no medicare trust fund. All the trust fund is a record of how much extra tax was paid in the past----ie how much money got diverted into the general fund and spent on other things.
So Medicare and Social Security resemble peak oil in one important way----its not when the trust funds run out that matters----the important thing is when the expenditures begin to exceed the tax income.
Just as in the POD where problems start not when oil runs out but when demand exceeds supply, SS and Medicare are in trouble when spending outpaces tax revenue.
For social security we hit that in 2010. Obama's new 2% tax hike in SS taxes will help but may not be enough to solve the problem---we'll have to wait and see if the SS budget balances for 2013.
Medicare is the same thing----delaying the exhaustion of the trust fund to 2026 does't mean a thing---the key date is when spending outpaces tax revenue. And thats is going on right now.
Medicare spending exceed tax revenue right now----!
