USA Today notes a decline in the percentage of people who expect to receive their Social Security benefits. The first sentence of the piece implies that the loss of confidence is due to that fact people have been: "battered by high unemployment and record home foreclosures."
While the recession could explain the loss of confidence in Social Security, it is also possible that the huge public relations campaign by Peter Peterson and others has played a role. Peterson, a Wall Street investment banker, has pledged $1 billion to a foundation that has cutting Social Security and Medicare as its major goals. He has spoken widely around the country telling people that Social Security is going broke and that it has no trust fund. He has enlisted prominent political figures, including former President Bill Clinton in this effort.
There are other efforts to undermine public confidence in Social Security, most notably President Obama's deficit commission. Former Wyoming Senator Alan Simpson, one of the co-chairs of this commission, has also frequently insisted that Social Security is going broke.
It is possible that these public relations efforts have had their intended effect of undermining confidence in the Social Security. The article should have at least noted this possibility.
