And it's not like the United States is alone in making this change. All over Europe, countries have already or are considering raising retirement ages to save money.

"Retirement age has to be on the table. It will either get incorporated into law in this round of fiscal reforms or in the near future," she said. "There's no way we can support people as they live longer. And it's an issue that is becoming less politically charged."
