What you paid in Medicare taxes shows up on your W-2 income tax form every year. So when you retire, you want your money's worth.

That's how most Americans see it. In an Associated Press-GfK poll nearly 6 out of 10 said they paid into the system so they deserve their full benefits - no cuts.

But a newly updated financial analysis shows that what people paid into the system doesn't come close to covering the full value of the medical care they can expect to receive as retirees.
