This article, which links to sources that may or may not be genuine or accurate*, makes quite a few interesting statements.
I don't know how true it is, but I don't doubt the vast majority of the statements. Some of them that give one pause for thought:
2. According to one recent poll, 25 percent of all Americans in the 46 to 64-year-old age bracket have no retirement savings at all.
8. Today, one out of every six elderly Americans lives below the federal poverty line.
13. A poll conducted by CESI Debt Solutions found that 56 percent of American retirees still had outstanding debts when they retired.
34. According to a recent survey conducted by Americans for Secure Retirement, 88 percent of all Americans are worried about "maintaining a comfortable standard of living in retirement".
That last one is at least a little bit encouraging. At least most people are aware that something is wrong. Maybe a few of them might actually do something about it.
