Clemens Kownatzki at  Business Insider has some wonky charts about Greece's demographics, and how  their unsustainable economic situation is only exacerbated by their aging population. Kownatzki applies this to the situation in the U.S.
Temporary measures for bailouts and economic stimulus packages are one thing, but without drastic measures, ongoing government deficits are simply not sustainable for the simple fact that people live longer and there are not nearly enough young people joining the work force to generate sufficient government revenues and to support the growing unfunded liabilities.

...The US projected demographics are not nearly as bad as Greece but the thought of having 13% of men and 17% of women over the age of 70 makes the current US retirement age a near impossible proposition
This makes me fee awfully good about my economic future...
